Yo! I’d like to become a Star developer if possible.
Currently, I publish several theme Snaps, whether GTK themes, icon themes, or cursor themes.
I’ve also made Snap versions of some apps, such as MPC-QT, Strawberry, Engrampa, lxqt-archiver, Bluejay, some emulators, and games.
You can see everything here: https://snapcraft.io/publisher/kyuyrii
The contributions I remember making to Snap apps that aren’t published by me were just small changes/improvements to Steam, Shotwell, gtk-theme-pocillo, and gtk-theme-qogirbudgie.
