This plugin as well as it's brother available on stylus is amazing. I appreciate all the work you do to make youtube so much better for all of us. Just noticed today after waking up that the UI for Theater mode specfically is causing the Play/Pause buttons as well as the the entire video UI to be slightly larger. When switching back to from theater mode to normal mode, the buttons are back to the normal size. I hope there is an update in the future to remediate this annoying "feature" youtube has added to theater mode. Again appreciate all your work so much I can't even put it into words lol. Edit: Oh and you have to be out of fullscreen specifically only in Theater mode for this to occur. Since I use the "Enable ambient mode in Theater" setting with your plugin now I've noticed this just happen today. Edit: This specific ublock filter fixed my issue with the bigger buttons. Maybe this could help create a "Theater mode" UI fix of some sort? Filter: www.youtube.com##+js(rc, ytp-big-mode, , stay)
