That’s sort of how herbstluftwm models it. Workspaces are called tags, and are areas windows can be arranged. Monitors are like SVG viewports, with dimensions; Herbst auto-manages physical monitors, but lets you define virtual monitors with arbitrary dimensions. Workspaces (tags) are displayed on monitors and windows are adjusted to the dimensions of the monitors as tags are moved around. Monitors can be overlayed… the terminology is counterintuitive (windows have tags, but can only have one tag at a time, and monitors can overlap, etc), but it’s a really nice way of approaching things IMO, and is one of the main reasons I’m sticking with X.
