Files menu sub menus #4828
Description
This is quite similar to #462, but specifically for the files menu, although a more generic implementation could solve both issues (at least partially).
Being able to organize the Files menu shortcuts into sub menus would be extremely nice in cases where there are lots of menu entries and the menu ends up covering most of the screen, sometimes even overflowing.
Our main use case here would be either to organize them based on the project/group, or based on disk area.
I did a quick mock-up that perhaps visualizes the idea more clearly:
The same shortcut structure would be nice to have in the file browser itself. Some titles in the files browser shortcut list and indentation would probably work fine.
