the one thing that's flawless for me is the screen rotation
Really? So you can watch videos horizontally without the video randomly flipping to vertical and back?
I've tried messing with the settings, but it doesn't seem to do anything. See this bug report, finding that setting was a nightmare, and it didn't even do anything. If it was open source, I'd probably go make a fix, but it's not, so I guess I'll just complain about it.
And yeah, that menu sucks as well. I hope Futo hires a UX person because it could be so much nicer to use. I'm impressed at how well it works though, so that dev is doing a top notch job.
