Michael, I think it would be great shortcut if (when having split view) right-click on viewport (top/bottom, right/left, back/front) would cause just flip that viewport view.

I use split view basically all the time and often switch between views as mentioned.
Now I have to click 3 times to switch top to bottom or others.

I know that it saves just 2 clicks and like 0.5 second (each time), but screen flashing is also quite unpleasant when clicking.

Or if you can let me know of other shortcut to achieve this it would be great.

EDIT:
I just found script for that. But built in function would be great and I think it wouldn't take much time to integrate as native.

Regards,
Juraj
