Not sure you should even be allowed to advertise legal things except in very specific cases. It's an incredibly toxic industry that is doing a shitload of the heavy lifting of corporations destroying the world..
Personally how the app looks isn't much of a priority unless it's so bad that it hurts usability and maybe 7/10 times I tried to play a video in Libretube it would either hang for at least a minute or fail to play at all.
That's just not an acceptable tradeoff for looking slightly better than NextPipe that's near-flawless on my phone and SmartTube that's near-flawless on my tv, neither of which is bad-looking IMO 🤷
Her taxes. She's VERY good at multitasking!
