In Windows 11 there’s a button on the taskbar next to the start button that lets you switch between multiple desktop environments. It seems like something that would probably be useful in theory, but I can’t think of any reason why I would want to use it. Is it actually useful? What do people use it for?
Just wait for Plasma 6.0, it’s already there available out-of-box (except auto creating new workspace for fullscreen window)
