  212.  
  213. 	// CHANGELOG:
  214.  
  215. 	// **4.0.0b** Numerous additions, improvements, and massive internal changes. Virtually no line of code has been left untouched.
  216.     // **"b" === "bugs" likely. Updates will be coming.
  217.     // **IMPORTANT:** This version uses a new format for user settings in the code; you will have to re-enter your defaults manually after updating.
  218.     // - Do NOT use exported settings from any earlier version of the script.
  219. 	// **NEW:** Added independent text editor pane.
  220. 	// - Invoke with Cmd/Ctrl + E, or in main menu > Text Editing > Toggle Text Editor", or under "Show Details".
  221. 	// - To prevent loss of work (and for convenience, e.g., to refer to a file while writing), previously entered text will not be cleared when the "New" button is clicked again, when the "Close" button is clicked, or when a sidebar item is selected.
  222. 	// - Use the Save button to save the text as a text or html file, which can be previewed and edited as usual by navigating to its saved location.
  223. 	// **ADDED:** Option to number index items, with new user setting.
  224. 	// **ADDED:** Stats footer in sidebar showing dir and file count.
  225. 	// **ADDED:** Icons for shortcuts menu to indicate local vs. remote links.
  226. 	// **ADDED:** Text editing: Clear button to empty text editing pane.
  227. 	// **CHANGED:** Text editing: Github styling customizations: Make table cells top-aligned, darker blockquote text color.
  228. 	// **IMPROVED:** Text editing: When saving rendered HTML, header uplinks will be removed.
  229. 	// **IMPROVED:** Text editing: Don't close other previewed content when making new text editing pane.
  230. 	// **IMPROVED:** Text editing: Much improved warning system for edited text: now uses `postMessage` to communicate between iframe and parent.
  231. 	// **IMPROVED:** Content display: use the same code to prep and style directory contents in the preview pane.
  232. 	// **IMPROVED:** Live sorting of grid items (but images and fonts are still sorted separately).
  233. 	// **IMPROVED:** Image zoom positioned accurately under click.
  234. 	// **IMPROVED:** Better handling of 404 Errors (Page not found): server error message will appear in sidebar, warning icon in content pane.
  235. 	// **IMPROVED:** File URLs: If a file URL (instead of a directory) is entered directly in the browser URL bar, the parent directory will be loaded instead and the file automatically selected.
  236.     // **IMPROVED:** Navigation: modifed highlighting styles to show when a non-audio item is selected for navigation vs. when it is loaded in preview pane but not selected (e.g. click a directory and then click an audio file; the directory item will be dimmed).
  237.     // **IMPROVED:** Audio: Greatly simplified shuffle play code and fixed several bugs; shuffle list now correctly updates when individual audio tracks are checked or unchecked.
  238. 	// **CHANGED:** Moved scale buttons and prev/next image buttons to preview title bar.
  239. 	// **CHANGED:** Sort by "Name" always sorts files and directories together; "Default" sort always keeps files and directories separate.
  240. 	// **FIXED:** Text editing: Some issues with split-pane resizing.
  241. 	// **FIXED:** Cmd/Ctr+W (close) should work now: previewed content will be closed first, then audio, then the browser tab itself.
  242. 	// **FIXED:** Don't autoload audio cover art when next audio track begins; i.e., leave open whatever file is being previewed, including cover art or lyrics.
  243. 	// **FIXED:** An issue with sorting by size.
  244. 	// **FIXED:** An issue with the user UI font setting.
  245. 	// **FIXED:** Navigation by typed string now correctly scrolls directory list.
  246. 	// **OTHER:** Many small style fixes and tweaks. Among others, make the previewed image and image grid background color light in default theme.
  247. 	// **INTERNAL:** Complete code overhaul.
  248. 	// - Completely rewrote the code that preps the served directory index for processing by the script.
  249. 	// - Completely rewrote and simplied the sorting code.
  250. 	// - Alphabetized User Settings for easier editing.
  251. 	// - Fixes for additional server index configurations.
  252. 	// – Performance improvments (e.g., removed multiple calls to various functions, reduced initial DOM manipulation, etc.).
  253. 	// - General code cleanup (e.g., removed unused variables and unnecessary globals, named many formerly anonymous functions, fixed numerous syntax errors, etc.).
  254.  
  255.     // **STILL TO COME:**
  256.     // - Dark mode for text editing.
  257.     // - Additional code cleanup, and more.
