New features, improvements and a few fixes

This version includes two new features:

Show channel video count next to the subscriber count in the video page. The text is also converted into a link directing to the channel video page.

Note: It is possible the video count might not show for some users because YT changed their UI recently, and this will be addressed in the next update. The link feature still works correctly in both cases.

Option to enable the ability to change volume using scroll by holding the shift key. This option allows users to select between scrolling over the video to change volume, or holding shift + scroll to change volume from anywhere in the page.

A few improvements and fixes are included in this version:

Player shortcuts (K key and spacebar key) now work with autoplay disabled
Ensure extension settings apply when the video refreshes its streams when they expire after 6h
Fixed black screen showing on scheduled livestream instead of the thumbnail and reminder button
