The right-hand panel will show an article's associated "tags". Can something similar be done for folders since not everyone is into the "tag "functionality. Many of us still use folders!
With a growing library, I often have the situation of finding (via the search field) that a paper is in my library. When I click "View in Library" I only find it in the topmost folder (actually have to scroll endlessly to find it at all!) but then do not see in which subfolder the paper actually is.
One could ask: if I've already found it, why bother in which subfolder? Because I wanna make sure it is sorted where it belongs!
