BTRFS, GUI Flatpak manager, Theming, nonfree codecs etc., printer support, timeshift preconfigured
Their goal is to make vanilla debian usable, with only debian tech. It is just a config, no “small distro dies and users need to switch”
Might not be the most secure (loose printer configs, preinstalled drivers for random stuff that is not normally a problem)
Shared folders are easy with Linux guests, you just set it up in virt-manager and then mount it in Linux. With windows it’s possible and I have done it but you need to install the virtiofs driver alongside winfsp and then make sure the virtiofs service is running. So the setup is definitely a bit obtuse. I haven’t done clipboard sharing deliberately as I don’t love the idea of that being synced but I should at least try it so I know what setup is like. The file sharing isn’t hard once you learn how to set it up but figuring it out the first time is a challenge for windows guests.
I will see if this is documented and maybe try to improve it.
Docs are important!
