Allow favourites to load offline

So i favor the files that im using quiet frequently. So i can access it fast via favourites.
I also have them synced (cause they my favourites that i use very often and i don't have mobile Internet)

So i would like to be able to filter for my favourites also/especially when im offline (even if i only find my local ones then).

Btw. Hudge thanks to whoever made the favourites load in one try and without 15 sec of flickering before! ( thats hudge progress!)
