Click to expand the changelog at the time of 4db30e8

• Added features:
  • Keep the volume synced between tabs
  • Set an initial volume level once per tab
  • Hide the cursor after a set amount of inactivity while hovering over the video
  • Show a thumbnail overlay over the video element (or open the thumbnail in a new tab) automatically and/or manually, depending on configuration
  • ?si parameter is removed in YT's share menu too now
  • Added an "above-queue" button to clear the currently playing queue / playlist
  • Fix rendering issues when using HDR
  • Disable the Dark Reader extension on both pages (because it messes up the layout)
• Changes / Fixes:
  • Improved the config menu
    • Created new toggle input (because checkboxes don't come close to looking as good)
    • Added an advanced mode option that reveals a set of hidden settings, and lots of new settings that were previously not configurable
    • Improved styling and layout of menu substantially, especially when using different languages
    • Now an option to open the config menu is shown on YT too
    • Made a bunch of features not require a page reload anymore
  • Fixed tooltip that is set on the wrong element
  • Fixed queue buttons not being shown when navigating with tab key
  • Tons of accessibility improvements for screenreader users (feedback regarding this is strongly welcome!)
• Internal Changes:
  • Improved script performance
    • Implemented new SelectorObserver instances to improve overall performance by quite a lot
      • Implemented rising-edge debounce for SelectorObserver instances to massively improve responsiveness
    • Added a cache to save lyrics in. Up to 1000 of the most listened to songs are saved throughout sessions for 30 days to save time and reduce server load.
  • Implemented new class BytmDialog for less duplicate code, better maintainability, the ability to make more menus easier and for them to have better accessibility
  • Expanded plugin interface
    • Added function to register plugins (see contributing guide)
      All plugins that are not registered will have restricted access to the BetterYTM API (subject to change in the future).
    • Plugins are now given access to the classes BytmDialog and NanoEmitter, and the functions onInteraction(), getThumbnailUrl(), getBestThumbnailUrl() createHotkeyInput(), createToggleInput() and createCircularBtn()
  • Added an experimental fuzzy filtering algorithm when fetching lyrics to eventually yield more accurate results (hidden behind advanced mode because it's far from perfect)

_{This version is almost finished but may still contain a few tiny bugs.
It is highly recommended you fully remove the script and reinstall it manually once the update is released.}
