Feature idea: combining workspaces

[agnosthesia]

As a long-time dwm user on Linux, one of my favourite features comes from this patch: https://dwm.suckless.org/patches/combo/

In dwm terms, the workspaces are called tags. This allows you to show multiple tags at once (for example, all the windows on workspace A and workspace B).
I would often use this in roughly the same pattern:

• Have some fullscreen window, or several tiled windows that I want to stay put
• "Combo" in another set of floating windows briefly, then put them away

For example, while screensharing in a presentation I could show my slides but occasionally put a couple of terminals on top of them to demonstrate something, or switch to a browser window or video without the transition looking clunky (as the windows swap or try to share real estate while all tiling).

I would really love if aerospace had a way to do this, either something I could do already via configuration that I have not realized, or some new development of this feature..

Would this be straightforward to implement?
Any interest/questions about it?

I came here to make this same request!

To expand/clarify, in something like awesomewm, I have my terminal in workspace 1, browser in workspace 2, Emacs in workspace 3.

Often I want to see the browser and one of the other two (terminal/Emacs) at the same time (e.g. following instructions in the browser and executing in the terminal). With awesomewm, I could tell it to combine workspaces 1 and 2, and it would tile the terminal and the browser. If you then explicitly switch to any particular workspace, it would restore how things were.

I sometimes would do it with 3 or even more workspaces. The idea is that you just want to temporarily put them all in one workspace. With aerospace (new user), I have to move the terminal to the same workspace as the browser, and then move it back once I'm done. Once you're used to combining workspaces, this is tedious.

So I guess the request is: A way to combine 2 or more workspaces into a temporary workspace, such that when you leave that workspace, the temporary workspace disappears and the windows are back in their original workspace.
