Finding items that have been hidden

How does one find items that have been hidden deep in nested folders. In really large projects it can be really, really tedious to find and unhide a previously hidden item.

Well there is a sort function for bodies, sketches etc.

Organizing in folders by part type like fasteners etc. Or sub assemblies

I agree and have asked for a different eye icon on folders if there are items with their visibility off inside of them.
