Dynamic Folders & Used in Playlist

Hello mAirlist,
I have a feature request for folder in the mAilistDB. I would love to have a extra TAB in the folder with information in the playlist that folder is used.

And in the second TAB if possible a option for dynamic folders. Something like this i have in mind:

That would really help to keep the folders up to date, without all the manual work.

Thank you in advanced.
