Is there any update jomag's question now with macOS 10.15 (Catalina) or 11 (Big Sur)? I also very much like and often use the mentioned Ubuntu functionality and would welcome it on my iMac a lot!
+1 for this one.
This would be a killer feature and it is one area when for example windows 10 management of windows makes it so easy to create a window layout and than dynamically adjust all windows together.
