This addon could be very good and effective, but sadly it's bad, unreliable in conjunction with using containers, it disables itself and dark theme by itself, so one has to repeatedly reactivate the dark theme in addon, also problems with switching between the themes when screen res is 4k. Too bad this wasn't sufficiently tested before release

The in-browser config page isn't in dark mode by default and it makes me angry

It was working for a while but not it is bugged and sets my youtube into a refresh loop. The page constantly refreshes making it unusable.

Extension button always shows disabled and is always enabled regardless of clicking (intended to be a toggle switch). If you visit the youtube music it will reload over and over and wont let you use the site. All that said it did have a nice theme.

Good but it glitches out when I open the page to edit a playlist and keeps reloading all the tabs with YouTube. It also reloads the tabs when I re-enable the add-on after disabling it, wasting bandwidth and CPU resource.
