Using sonixd for desktop and finamp for mobile through my Jellyfin server and really liking it.
I did have to make a separate Jellyfin account for my music since I didn't want music showing up on the Jellyfin TV apps cluttering it up but not bad overall!
Finamp doesn't track new items in a playlist marked for offline play which is my main gripe atm.
I started with openscad and moved to freecad. Freecad is powerful but definitely not perfect but it has suited my needs fairly well.
I'm still a holdout for superslicer but I did migrate my profiles to PrusaSlicer for those sweet organic supports.
