There should be a integration to specific services like for YouTube or SoundCloud to utilize the next / prev keys on keyboards and in the tray widget. I know, that this can't be created universally, but it could be implemented for some services for now. Preferably: YouTube SoundCloud Spotify Web
I thought about it but this isn't really the scope for this extension. If a website implements the media sessions API this will work. I noticed that SoundCloud actually uses it but only registers callbacks for play/pause and seeking but not changing tracks for some reason
Closing this as "remind later" as this might become obsolete once websites start using media sessions API. I have seen Soundcloud use it already (albeit without the ability to change tracks) as well as Forbes
