Stackable / Overlapping Windows, like in Pop_OS for linux

Converted to Feature Request at…. #1403 (comment)

I was wondering if it is possible to have a Stack or Overlapping (“Stack” may be associated with another concept) set of windows, where all members of this set appear like Tabs, in a browser. I have used it in Linux (Pop! OS) and found it very useful alongside vertical and horizontal panels. Attached screen capture from Pop! shows what I am saying. Thanks
