Feature description

This is a specific feature request/continuation for a feature I mentioned in "issue #119."

When browsing gallery folder structure with "Direct subfolder grouping" enabled, show a path bar on the top to identify where you are located in the folder structure, with each level being interactable as a shortcut to backtrack.

Why do you want this feature?

It would help keep track of where you are in your subfolder structure as well as easily back-track to previous levels in the folder structure.
