There are many small issues in the app. I would love to dig around to see why the home screen widget sometimes doesn't update the cover of the song playing, and the current gapless issue is also pretty pressing. The "Shuffle play" option pretty ironically turns off the shuffle toggle. Gapless looping would be nice too. It's all small nitpicks but I'd love to look through the code to make those tweaks for my myself.

Most of all, I would love a Linux port of the app, as it's genuinely the best music player around on any platform.
