Stacking of subwindows in minimize panel makes it difficult to choose main windows

Hi, It’s one of the things which can be fixed to switch between multiple of open blender files.
The issue is when you open multiple blender files and all these files have subwindows (graph editor, driver editor etc.) opened, its hard to find which window is main window in minimize panel (when you are trying to toggle between different windows using alt+tab) as all the main windows and subwindows can be seen in the panel.
It would be nice if we can only see main windows in minimize panel.
Thanks for 2.8 . Happy blending :slight_smile:
