Way to Organize maps

This might have been talked about before, but i think it would be nice to be able to have folders for the maps i create for my players in the campaign. That way i can easily store them for later, and access my newest ones without having to scroll a long ways down the list. 

It's been mentioned before, but definitely good to repeat. 

They already have a "Folder" structure.  If they'd allow us to make our own "sourcebook" level categories, and allow us to choose what maps go in where, it would function just like people want.

As a note too, they'd have to fix Search so that you can search all categories instead of just the one you have open too.
