autoplay button sticking out of the player style
this effects all the player styles that arent the newest one. it probably happens because of the smaller formfactor these player bars took up, or that the autoplay button wasnt there back then. i really dont know.
It's because it wasn't there back then. Will look into it eventually, but I can't say when.
YouTube Redux has the autoplay button where it's supposed to be
Yes I know. I eventually plan to do that as well, but it hasn't been a priority yet. Now that you've mentioned it though, I'll try to get to it sooner.
use ublock to disable the autoplay button like i did
