So 24 hours later this is running as well as the Pi OS, only real difference are minor, 1: Kodi freezes on Mate ( Pi uses a special adapter and came from Pi apps ) and 2: Unlike Cinnamon where I can have extra drive applet in the panel bar, it looks like I can only have them on the DT in Mate.
Is there a way to install PiApps to UM ?
Last question, I added Timeshift, but I hit create before doing some settings and it placed the folder in the home folder, can I just move the folder to a SD or ext. drive ?
Really happy so far with Mate on the Pi.
