Displays share the same workspace

[antran22]

Right now, the behavior of Aerospace mirrors "Displays have separate Spaces: on" setting of native MacOS Space. Which mean, each workspace is assigned to one display only.

My proposal is to have something similar to "Displays have separate Spaces: off". By enabling this, each workspace is bound to every displays available. When switching workspace, all the windows on all displays will also be changed.

Implementation idea: We can augment the current implementation of workspace for this kind of behavior

• Introduce a "super-workspace" entity, which contains multiple workspaces, each bound to a display.
• When switching "super-workspace", we simultaneously focus to all the workspaces of the new "super-workspace"

Difficulties with this approach

• We need to add-remove the workspaces in each super-workspace when new displays are added-removed from the device. Also move windows in each removed workspace to the remaining displays.
