If you have a KDE dev account and want to contribute, feel free to do so
But, obviously, if you want to work on a new feature, it would be better to first talk to me to see if this align with the general idea of the project
Donation, no need for money, unless you really love the project and absolutely want to give something to me. I'm just a student who want to share it's work to make it better :-D
Yes please, test the app, I'm always looking for constructive criticism !
