  17.    // E.G.: For Tampermonkey in Chrome, go to Chrome the extension page, click the details button on the Tampermonkey pane and check 'Allow access to file URLs'.
  18.    // NOTE: Safari does not allow local directories to be browsed, so the script will not work on local directories, but it will work on remote directories (or on local directories through a local server).

  20.    // It has been very minimally tested on Windows and not at all on other OSes or browsers. It should work, but please report any issues.

  156.     // CHANGELOG:
  157.  
  158.     //• 3.0.0
  159.     //• NEW: Support for video playback (finally!). Default supported video extensions: .mpeg, .mov, .m4v, .webm, .mp4 (add additional extensions below in $row_types > video).
  160.     //• IMPROVED: Cover art auto-selection: files with "back" in the name will be ignored and files with "front" or "cover" in the name will be selected.
  161.     //• IMPROVED: Directory preview styling.
  162.     //• IMPROVED: Better support for Firefox.
  163.     //• ADDED: "Autoload media" menu item.
  164.     //• CHANGED: "autoload_audio" renamed to "autoload_media"; if you export your user settings, please this update this item accordingly when you paste them back in.
  165.     //• CHANGED: Completely reworked arrow navigation and autoload_media behavior because previous behavior was confusing.
  166.       //• Up/Down Arrows will now always select the prev/next row.
  167.         //• If the audio player is not visible, it will be displayed and the selected audio file will be loaded for playback.
  168.         //• If audio is playing and the prev/next selected file is also audio, it will be selected but not loaded, so that the currently playing audio will not be interrupted. (Press return/enter to load and begin playback of selected audio.)
  169.         //• Selecting audio files deselects video files and closes video player.
  170.         //• Selecting video files deselects audio files and closes audio player.
  171.       //• Left/Right Arrows will now always select the prev/next row of the same sort kind as the currently selected file, except:
  172.         //• if the current selection is an audio file, the L/R arrows will select and begin playback of that selection.)
  173.         //• Note that if the current selection is _not_ an audio file, any currently playing audio will continue without interruption.
  174.     //• FIXED: Media files did not scroll into view when next file began playing.
  175.     //• CHANGED: Autoload cover art now works irrespective of "autoload_media" setting.
  176.     //• IMPROVED: Left/Right arrow navigation will select prev/next dir or row if there are no media, image, or font files are in the directory.
  177.     //• IMPROVED: You can now close previewed content and audio files separately from each other.
  178.     //• CHANGED: Audio file titles shown separately from other file or dir titles.
  179.     //• IMPROVED: Added string normalization for navigation by typed string: accented characters will be matched by their base ASCII letter (e.g., á = a, Ñ = n, ß = s, etc.).
  180.     //• IMPROVED: Added "other" sort category for files whose extensions are not listed in $row_types.
  181.     //• FIXED: Parent links were incorrectly formatted.
  182.     //• FIXED: Arrow buttons in preview pane were not working properly. Now, if an image or font is displayed, clicking the arrows will select the prev/next image or font file.
  183.     //• ADDED: Contact link in shortcuts menu
  184.     //• FIXED: "Donate" link.
  185.     //• Fixes for various style glitches introduced in the last version.
  186.     //• Many, many small fixes.
  187.     //• CHANGED: moved $row_types to just below user settings, for easier management and updates.
  188.     //• Internal: Reorganized, abstracted, and DRYed many functions; added more comments.
  189.  
  190.     //• 2.7.1
  191.     //• Added: User settings to choose default UI font-family and UI font size.
  192.     //• Added: User setting and menu item to alternate sidebar row background color.
  193.     //• Improved: Directory preview styling: alternating row background, font-family and font size honor UI settings.
  194.     //• Internal: Completely reorganized CSS by declarations instead of selectors (DRY CSS).
  195.     //• FIX: Font previous sometimes forgets dark mode?
  196.  
  197.     //• 2.7.0: New features and user settings. Please export your user_settings before updating and note the changes mentioned below.
  198.     //• NEW (and experimental): Display a standard index of the selected sidebar directory in the preview pane.
  199.     //       This is very handy for browsing directories from the sidebar.
  200.     //       Clicking files and directories directly in the preview pane works as you'd expect, but it can be a little weird,
  201.     //       since you can navigate up and down the directory structure in the preview pane independently from the sidebar.
  202.     //• NEW: Added URL query strings to remember directory selection history and various temporary UI settings between directory changes:
  203.     //       sort order, show/hide details, default/dark mode, sidebar width, and previously selected directory.
  204.     //• NEW: Select files and directories by typed string.
  205.     //• Improved: Converted user shortcut settings to JSON for greater flexibility.
  206.     //            Now you can create and name your own shortcut menu categories.
  207.     //            IMPORTANT: You must re-enter your old shortcuts in the new settings format.
  208.     //• Added: Menu item to reset/delete query strings and return to the default user_settings in the script.
  209.     //• Added: New user setting to show/hide details by default. (Don't know why it took so long to add this.)
  210.     //• Added: User customizable file kinds for sorting.
  211.     //         You may add or remove file kind categories and file extensions to suit your own files:
  212.     //         See "$row_types" in code below, at the beginning of "General Setup" and just after the Changelog, to add your own.
  213.     //• Removed "ignore_file_types" from the user_settings, because the list of ignored file extensions has been moved:
  214.     //           See "$row_settings" in code below, at the beginning of "General Setup" and just after the Changelog, to add your own.
  215.     //• Removed "user_name" from the user_settings, because it is no longer needed.
  216.     //• Improved: File shortcuts work much more reliably now, and thanks to query strings, you can now bookmark more than one file in a directory.
  217.     //• Improved: Various small UI changes.
  218.     //• Fixed: Toggle sidebar wasn't working.
  219.     //• Fixed: Ignored files weren't being sorted.
  220.     //• Internals: Abstracted a bunch of functions, removed some unneeded variables and functions. More to be done.
  221.     //• If you like this script, please consider making a donation. See the "Donate" menu item. Thanks!
  222.  
  223.     //• 2.6.5
  224.     //• Fixed: First and last audio files would repeat when ended instead of going to next track in some circumstances.
  225.     //• Fixed: Various issues with file navigation.
  226.  
  227.     //• 2.6.4
  228.     //• Added: Nice custom icons for dirs and various file types. Other minor UI tweaks.
  229.     //• Added: New user setting to use default file icons instead the new custom ones, in case you don't like them.
  230.     //• Added: Separate close button for audio player, since there was no way to close it while leaving other previewed content open.
  231.     //• Fixed: Really, really fixed reload button and reload shortcut not working (I hope).
  232.     //• Fixed: Yet more issues with arrow navigation.
  233.     //• Fixed: Various UI issues with Firefox.
  234.     //• Improved: Sidebar resizing should be more reliable (drag event was interacting with sidebar).
  235.     //• Other: Abstracted some styles and cleaned up code.
  236.     //• Many other bug fixes.
  237.  
  238.     //• 2.6.3: Minor UI improvements and bugfixes.
  239.     //• Changed: Open dirs on double-click. (You can still open them by selecting and pressing "Return" or the Right Arrow Key.)
  240.     //• Changed: Removed autoplay_audio preference.
  241.     //• Fixed: Reload button and reload shortcut weren't working correctly.
  242.     //• Fixed: Clicking audio file name didn't pause/play file.
  243.     //• Fixed: Sidebar height didn't reset when changing sort order.
  244.     //• Fixed: Directories with a "." in the name were being sorted as if the trailing text was an extension.
  245.     //• Fixed: Corrected some code that prevented the script from working in Safari; while Safari still doesn't allow local directories to be browsed, the script will work on server-generated pages.
  246.     //• Other: Removed some unneeded styles and functions, simplified arrow navigation code.
  247.  
  248.     //• 2.6.2: Fixes for a few more pesky bugs. Just when you think you're safe.... Apologies.
  249.     //• Fixed: Reload and Close buttons and keyboard combinations now work for audio files.
  250.     //• Fixed: Preview pane titlebar wasn't showing in some circumstances.
  251.  
  252.     //• 2.6.1: Hopefully fixed a bug when navigating folders containing audio files. Sorry about that!
  253.  
  254.     //• 2.6.0: Sorting, new user settings, and much more! This is a pretty substantial update.
  255.     //• Added: Donate link (paypal.me/mschrauzer) to the main shortcuts menu. If you like this script, please support its development. Thank you!
  256.     //• Added: Support for additional common server-generated index types. The script should now work on index pages structured as unordered lists, "<pre>" text, and html tables.
  257.     //• Added: Sorting by name, size, date modified, kind, file extension, and default Chrome sorting (i.e., dirs on top, files alphabetical).
  258.     //• Click the "Details" button (or Cmd/Ctrl + D) to show the available sort options.
  259.     //• Note: Some server configurations don't provide size or date information; on such sites, these sorting options will not be available.
  260.     //• Note: Sorting by kind is based on the file extension, so it is rather coarse (at least for now); many non-image/audio/pdf files will simply be categorized as generic "Files".
  261.     //• Added: Added "Sort by..." menu item in the main shortcuts menu.
  262.     //• Added: New User Settings (gives you control over some behavior added in the last update):
  263.     //• default_sort: Choose default sort method: by name, size, date, kind, extension, or Chrome default (dirs on top, files alphabetical).
  264.     //• dirs_on_top: Choose whether directories should be sorted separately from files.
  265.     //• autoload_index_files: If true (default false), autoload first index.[ext] file found in directory.
  266.     //• autoload_media:
  267.     //• If false (default), treat audio files like other files for navigation purposes. Use up and down arrows as normal, only show audio controls when an audio file is selected.
  268.     //• (Note that when false, only one file in the directory at a time can be selected.)
  269.     //• If true, autoload first audio file in directory (and cover art, if any) and navigate audio with left and right arrows, other files with up and down arrows. This was the previous behavior of the script.
  270.     //• Added: Alert reminder to add your computer user account name to the settings.
  271.     //• Enhancement: UI: Added flyout submenus to main shortcuts menu.
  272.     //• Enhancement: Added .aiff, .ape, .m4a to recognized audio format types.
  273.     //• Enhancement: Added .svg to recognized image format types (they now are shown in an <image> element instead of an <iframe>).
  274.     //• Enhancement: Moved the user settings to top of the code for easier access.
  275.     //• Changed: Since the browser can't tell if an mp4 file is video or audio only, all mp4 files will load in the main preview area, not the audio player.
  276.     //• Fixed an issue with image zoom.
  277.     //• Fixed an issue with previewed content not being removed when content of another type was previewed.
  278.     //• Internals: The script now converts server-generated index pages to the default Chrome table structure. Conversion happens in memory, so performance should be improved.
  279.     //• Todo: Better video file handling.
  280.  
  281.     // 2.5.0
  282.     // A whole bunch of small and not-so-small additions, changes, bug fixes, and enhancements.
  283.     // Added: Automatically load /index.[ext] files in the preview pane, if one exists in the directory.
  284.     // Added: Initial support for AMMPS index pages; added "localhost" to @include rules.
  285.     // Added: New user setting for external (non-local) shortcuts. Don't delete this item when pasting in your exported settings.
  286.     // Added: Show/Hide sidebar. Hidden sidebar can still be navigated by the arrow keys.
  287.     // Added: (Shift +) Alt/Option + Left/Right Arrows to skip audio ±10 or 30 secs.
  288.     // Added: Also use the Prev and Next arrows to navigate font previews.
  289.     // Added: Checkboxes for video files. Video file handling is still a bit of mess when audio files are also present in the directory; I will address this in a future update.
  290.     // Added: Images can now be scaled (instead of just zoomed by clicking) with the +/– buttons and the scale keybindings.
  291.     // Improved: Better scaling overall for images, fonts, and grids (use geometric instead of arithmetic scaling -- duh!).
  292.     // Improved: Auto-file selection from user file shortcut list. First file found is loaded; user file shortcuts take precedence over autoloading index files.
  293.     // Enhancement: Reload button also resets size of scaled images, fonts, and grids.
  294.     // Fixed: Some lingering issues with arrow navigation and audio files selection.
  295.     // Please read the updated list of keybindings in the description.
  296.  
  297.     // 2.4.2
  298.     // More audio file enhancements:
  299.     // Added: Checkboxes to play or skip specific audio files. (Such a seemingly small thing, such a pain to implement.)
  300.     // Added: Start/stop play by clicking file name.
  301.     // Added: Use Reload button and reload keybinding (Cmd/Ctr-R) to return audio to beginning of track.
  302.     // Changed: Don't autoplay audio when using left and right arrows to navigate tracks.
  303.     // Fixed: Various issues with shuffle play.
  304.     // Fixed: Completely rewrote autoload cover art code so that it actually works.
  305.     // Fixed: Ignored files weren't being ignored in list-based index pages.
  306.     // Many other bug fixes.
  307.     // Minor UI adjustments (e.g., better prev and next track buttons).
  308.  
  309.     // 2.4.1
  310.     // Added: Loop and shuffle playback for audio files.
  311.     // Added: Wrap-around keyboard navigation for audio tracks.
  312.     // Added: Default background image for audio directories containing no image files.
  313.     // Fixed some scrollIntoView issues.
  314.     // Fixed auto-cover image selection issue in Firefox.
  315.     // Bug-fixes. Yep, bug-fixes.
  316.  
  317.     // 2.4.0
  318.     // Major update for audio files!
  319.     // New: Play all audio files in a directory.
  320.     // New: Autoload cover art files (if available) in the preview pane. The script will look in the directory for image files titled "cover.[ext]" or "front.[ext]"; if they are not found, it will load the first image file it finds.
  321.     // New: Audio file keyboard controls: Left/Right Arrows to navigate tracks, ignoring other files in the directory. Up/Down Arrows to navigate and preview all non-audio files in the directory (e.g., cover art or lyrics). Space bar to pause/play. (Note: grid-view is available in directories containing audio files, but the left/right arrow keys will not select grid items.)
  322.     // New user setting: autoplay audio files. Default is false, but if true, the first audio file will start playing as soon as the directory is loaded. Again, don't delete it when pasting in exported settings.
  323.     // Some code cleanup and bugfixes.
  324.  
  325.     // 2.3.0
  326.     // Added: New user settings: default grid image and font sizes. Don't delete them when pasting in your old exported settings!
  327.     // Added: Scale grid image items.
  328.     // Improved: Better image zooming. Zoomed images now scroll to the area clicked.
  329.     // Fixed: Keybinding to toggle invisibles wasn't working.
  330.     // Fixed: Image zoom not working.
  331.     // Fixed: Hovered background for grid items in dark mode.
  332.     // Fixed: Font scaling in dual grids.
  333.  
  334.     // 2.2.0
  335.     // Added: Export settings menu item. This will make it easier to save your user settings before updating the script. (Remember, scripts running on local files cannot set cookies or use localStorage, which would make it possible to save user settings automatic.) Unfortunately, there is no mechanism for importing the settings: you'll still have to open the script editor and paste in the exported data.
  336.     // Fixed: File extensions were case sensitive, so some valid files wouldn't load if the extension contained capital letters.
  337.     // Fixed: File and Dir names were also being lowercased.
  338.  
  339.     // v. 2.1.1
  340.     // Fixed: Can't type "r" in font previews.
  341.     // Other minor bug fixes.
  342.  
  343.     // v. 2.1.0
  344.     // Added: Toggle Default/Dark modes menu item while browsing current directory; mode reverts to saved setting on dir change.
  345.     // Added: White background for images so that images with transparency are visible against the grey background
  346.     // Removed trailing "/" from directory display names.
  347.     // Fixed an issue where font and image grid display got confused about what content to display.
  348.     // Fixed directory names display in dark mode in server pages that use lists instead of tables.
  349.     // Better styling for grid button.
  350.     // Better styling for grid items in dark mode.
  351.     // Bug fixes.
  352.     // Remember to copy your user settings before updating!
  353.  
  354.     // v. 2.0.2
  355.     // Various fixes suggested by "Zorg":
  356.     // Dark mode now ignores html files (and media files), but inverts all plain text files. This solution is not perfect: there is a flash of inverted content when navigating from an html or media file to a non-html or media file; will look for a fix.
  357.     // Fixed display of non-Latin characters in sidebar header.
  358.     // Add support for linux "home" directory for user profile shortcuts
  359.     // Made entire up directory button clickable.
  360.  
  361.     // v. 2.0.1
  362.     // Fixed wonky font preview scaling.
  363.  
  364.     // v. 2.0
  365.     // NEW! Not just for local directories anymore! Added support for *many* server-generated directory index pages (It's impossible to check every server configuration, needless to say, so it might not work in every case; let me know if you encounter problems.// NEW! Preview font files (otf, ttf, woff, woff2). Great for designers: preview fonts without installing them. Hint: To install previewed fonts, just type Cmd/Ctrl + O or right-click the link and save it to your fonts folder. Font preview pane is content-editable.
  366.     // NEW! Preview font files (otf, ttf, woff, woff2). Great for designers: preview fonts without installing them. Hint: To install previewed fonts, just type Cmd/Ctrl + Shift + O or right-click the link and save it to your fonts folder. Font preview pane is content-editable.
  367.     // Added: Now use the Left and Right arrow keys to navigate through images and fonts in a folder, skipping other files. Use up and down arrow keys to navigate all files normally.
  368.     // Added: Basic dark mode user setting.
  369.     // Added: Wrap-around keyboard navigation.
  370.     // Added: Cmd/Ctr-D to toggle details.
  371.     // Added: Cmd/Ctr-Shift-. and Cmd/Ctr-Shift-, to scale font previews text size.
  372.     // Changed: Moved dynamically-added in-line styles to appended stylesheet.
  373.     // Changed: Extensive refactoring of code for better separation of concerns. (More needs to be done.... Sigh.)
  374.     // Removed: ScrollIntoView for Grid views. Scrolling didn't work reliably when the sidebar was also being scrolled. Will restore when bug fixed.
  375.     // Many small bug fixes.
  376.  
  377.     // v. 1.4
  378.     // Added: Initial support for Firefox. Tested in Firefox 59, Waterfox 56.
  379.     // Changed: Use SVG for menu icons
  380.     // Changed: Code cleanup, reorganization
  381.     // Renamed script to "Supercharged Local Directory File Browser"
  382.  
  383.     // v. 1.3
  384.     // Fixed: Keyboard navigation of ignored or invisible items fails if "Hide Invisibles" is toggled off after loading a directory.
  385.     // Added: Also hide ignored files if "Hide Invisibles" is checked.
  386.     // Added: Content reload button.
  387.     // Changed: Reorganized settings to reduce confusion about how ignored files are treated.
  388.  
  389.     // v. 1.2
  390.     // Click to show menus instead of hover.
  391.     // Added Cmd/Crl+Shift+O keybinding to open selected item in new window
  392.     // Arrow navigation bugfixes
