this one, OP. no need to introduce the horror that’s a:
- hosted app (why?!)
- client app is electron crapware
- the client app doesn’t even have full functionality, you have to use the web UI for some tasks
edit: I’m obviously speaking about the bitwarden/vaultwarden horror. keepassXC is none of them things.
mint uses X11 which should be considered legacy at this point. wayland (Gnome, Plasma) has all the touch and dock/undock and rotate and pen etc goodies. try it out from a liveUSB and decide for yourself.
