Ability to sort Layouts and Playlists into Folders

I find it really helpful to have Folders to organize things, just like you can with Apps. For Layouts and Playlists, there is no option to create a folder. Every time you make a change, that Layout or Playlist moves to the top of the first page, and there is no way (currently) to organize them. It would be very helpful to add a Create Folder option for Layouts and Playlists!
