[syeopite]

This is a meta-issue to track everything that needs to be done in order to fix the discrepancy between Invidious and YouTube's players

• [ ] End-cards
• [ ] Auto-generated captions (Follow up to: https://github.com/iv-org/invidious/issues/2187#issuecomment-866014531)
• [ ] Audio tracks (#2007)
• [ ] Channel Favicons
• [ ] Custom playback speeds (#533)
• [ ] Miniplayer (#583, #631)
• [ ] 3D
• [ ] Frame-by-frame skipping (#2113),
• [ ] Fine scrubbing (mobile-only feature on YT)
• [ ] Responsive design on both normal and embedded player
• [ ] Chapters
• [ ] Theater mode?
• [ ] Related videos in full screen? (useful for embeds and binge watching.) (Related issue: https://github.com/iv-org/invidious/issues/2431)

(Unrelated but having a milestone to track this in a more visual way might be nice)

I was waiting for the UI overhaul for so long until made a stylus css myself for player pages now it has full viewport width player and home. repo here

[davidcollini]

Is this able to be implemented in mainline invidious?

[debpalash]

i guess one could fork and inject my css 🤔

@debpalash FYI: I forked your stylus css; I removed and simplified some things. It can be easily extended further. You can see the source here, it's very short.

[debpalash]

@arjun44 nice 😂 . btw you need this to work on stylus @-moz-document url-prefix("https://instance.tld")

I'm not seeing YouTube Cards support in the list (example here). Is it planned?
