I’ve raged at the incompetent UX design so many times, like recently when I was trying to add videos to the currently playlist in a certain order, since you can’t reorder yourself. The mini player blocked the controls I needed for the last item on the page, but closing the player wiped out the playlist. Cue scream of rage and a few choice words at volume.
Their app and website are both atrocious. I’ve got a rant somewhere on Lemmy about once time it made me scream with impotent rage over the UX experience, and I’m someone comfortable with editing the DOM/scripting to fix the worst of it.
