My take on making LMMS blend in with the GNOME desktop
Most of the icons are still LMMS original, I have yet only changed a few. The heavy work is the css and the splash. There are still kinks that I am working on and I would like to work more with icons later on - so I'll keep updating this theme!
Installation
1) Download archive and extract Adwaita-dark
2) In LMMS, open settings -> folders and point the theme folder to wherever you put Adwaita-dark
3) Relaunch LMMS
