Feature Request - Folder View when using Android App

Hi.

Currently when viewing My Library then Folders, when I scroll down some way then go into a folder, when I leave that folder by hitting back, the view then returns to the top of the folder tree and I have to scroll down again to where I was alphabetically. 

If browsing Artists, behaviour works as desired - go into an artist starting with G as an example and when you come out of that artist you're still at artists starting with G.
