Which window managers support "detached" desktops?

# What do I mean by "detached"? In the herbstluftwm windows manager (and others, notably xmonad), the concept of a "virtual desktop" is removed from the physical monitors themselves. That means that any one monitor can be viewing any of the virtual desktops at a time. As an example, let's say we had three screens: [SCREEN 1] | [SCREEN 2] | [SCREEN 3] and 3 VIRTUAL desktops (in reality it's 9). [VIRTUAL 1] | [VIRTUAL 2] | [VIRTUAL 3] Now, imagine I have virtual desktop 1 on screen 1, virtual desktop 2 on screen 2, and virtual desktop 3 on screen 3. I want to be able to change the view to: [VIRTUAL 2] | [VIRTUAL 1] | [VIRTUAL 3] without dragging or moving windows in any way. herbstluftwm's rules are: * If you switch to a VIRTUAL desktop not already on another physical screen, it replaces the focused monitor's VIRTUAL desktop with the one you want. * If you switch to a VIRTUAL desktop that another screen is currently viewing, it will swap virtual desktops with that screen. * The focus determines which monitor gets its VIRTUAL desktop changed. If you have focus on screen 2 and switch to virtual desktop 8, screen 2 views VIRTUAL desktop 8. # What do other window managers do? The only other environments I have extensive experience with are Gnome and KDE. In both cases, **each virtual desktop is really a set of N screens**. So, with 3 screens and 3 VIRTUAL desktops, there are actually 9 "working areas". If I switch to VIRTUAL desktop 2 while the second monitor is focused, all three screens will change since screens are "bound" to the virtual desktop. There is no separation of screen and desktop. # What I'm asking First of all, is there a name for this type of functionality? I cannot work without it, and if herbstluftwm never supports Wayland then I'll be stuck on X indefinitely to get this feature. Second, which window managers support this? Are there hacks / workarounds where KDE or Gnome can behave like this?
