    We have some fix for the new Youtube Shorts layout.<br>
    Since youtube changed its own layout, we have to change our layout too.😑<br>
    We have added support for the light mode, now you can use Better Youtube Shorts in light mode.🌞<br>
    We added a new option: "Shorts Auto Switch To Video".📹<br>
    Tired of watching shorts? Turn on this option and you will be redirected to the video page automatically.🔀<br>
    If you have any feedback on the new UI, please leave a message in the Greasyfork feedback area.🍴<br>
