I just installed Ubuntu Mate 21.04 and i like it a lot. App menu works well, Yaru MATE is excellent, traditional desktop better than ever. But after about two week use, some ideas came to my mind. It should be a snap manager that can be accessed from the Software Boutique or from the control settings. Latest user should be able to easily edit the connections of Snap packages and change their theme or remove it. This can already be done from the terminal emulator, but it would be nice if something like this.
