While TeamViewer is definitely neglected I use it often on Wayland and it works well actually!

In the past year or so it doesn't shut down correctly. But the core functionality works well.

I've been experimenting with Rustdesk as an alternative because I doubt they'll update the Linux client anytime soon. The Windows version looks like an entirely different application at this point

In terms of feature parity. I believe the only thing left is global hotkeys, which hyprland proved it can be done.
