As of this month, some YouTube videos have 480p as the max quality while this extension is enabled. I disabled it and the problem disappeared. I'll rate it 5 stars once it's fixed.

It needs an option to add a scroll bar to the sidebar and stop leaving the home page blank when you hit the youtube button

One of the best tools to customise YouTube. But it has some issues. - Performance issues, it seems like my youtube is lagging after changing the appearance for youtube players. (player, comments, recommendation...) - Since this is a test extention, there are some scale problems with youtube recommendation below the youtube description. The grid seems like too small for me (i hope there's a way to change the size)

loved this extension but it's such a shame you reduced the max speed from 8 to 4. also why it speeds up music videos even though it shouldn't.

18일자 업데이트 후 모든 영상에 계속 반복이 적용됩니다 유튜브 쿠키까지 지워봤는데 새로고침하면 무조건 반복에 체크되어있네요 플러그인 비활성화를 해야만 해제됩니다. 그리고 컬러테마 변경했다가 다시 흰색으로 돌아올때도 정상적으로 안돌아오는 문제가 여전히 있네요.

For some reason it doesn't work anymore. I used the main Improve Youtube extension. This extension doesn't work either. Example: I can't change the theme into dark of any other theme. If I refresh the page the default theme returns.

The horizontal progress bar preview that is shown at the very bottom of the video when the mouse is away doesn't move or change till I move the mouse over the video. I switched to both the beta and non-beta version, I've uninstalled and reinstalled them, and it doesn't seem fix itself. It used to move a long time ago, that I remember clearly.

sidebar comments didnt work
