The option to disable Youtube autoplay does not work. The 'Completely stop videos instead of only preventing autoplay' option works as a stop gap, but then you have to refresh the page to get back to the previous video because the back button can't go back.
I found this extension looking for a solution to this specific problem and I did not find it, however everything else about the extension looks pretty good and I'm glad I found it regardless. -1 star for the disable autoplay not working, but if that issue is fixed I think this extension is 5 stars.

Recently, the definition setting seems to be malfunctioning. Even if the definition is set to 480p, the video still becomes 1080p.

"Convert Shorts" does not actually convert shorts until you have already navigated to the short and then refreshed the page. With this feature enabled, clicking on a short should automatically go directly to the short as a normal video. Until fixed, will have to use one of the many addons that actually provide this behavior.

Thank you for the app update. Bookmaked video does not work with the app, only when go to homepage and return does it work.
I have to click cinema mode to get full screen to edge video, is is a bug?

Would be fantastic to allow a mousewheel "scrub" (move through video) option e.g. when cursor is placed over timeline

Can confirm what Wronschien said. Changing all values of '#player-theater-container' to '#player-wide-container' makes Cinema Mode and Auto Expand work correctly. Tested on Nightly build.

sometimes need to refresh webpage because enhances stops working after skipping some part of video(only after buffering)

it's almost perfect but i'm missing a few tools still like flipping something from portrait to landscape view etc.
Fix those things and you get a purrrrrfect 5.

is there anyway to keep the controls off the video (no autohide, or dim, just plain move them below the video itself, so they dont get on the way of screen capturing software. I would like them to appear in the same control area of the enhancer buttons (below video area), or does anyone how to write script for that?

Amazing add-on. Basically the perfect thing for YouTube, but for a long time now it hasn't been working properly on different sites that have embedded YouTube videos. It wont automatically set things like quality, speed, etc. I can still activate it by doing things like using scroll wheel to set video speed and if I go into the add-on and switch on and off things it will then apply it to the videos. Would be amazing if you could fix these things!

works well
