To quote a line from the video from the recent treehouse meeting
“We should build a system that is migration friendly”
Currently the gallery module is not migration friendly as far as i’m aware there is no way to point a gallery to a folder and have it read all the items in that folder.
Happy to be told wrong 
If this is not the case, is it possible to get a back log item in there?
Definitely not user friendly int he current implementation.
