Just now I attempted to import a bunch of items that were largely differentiated by folders and sub-folders.
Once saved and shared to the collection, my wife asked me puzzled: “which one do I choose?”
Her screen had four items with the same name, where the only differentiator is the “password”
On my screen the folders tell me which is which.
I ended up trying to recreate the folders with collections. moving each item individually.
It would be better if collection items could contain their own folder data that is shared by participants.
Currently the user holds a list of items and which item belongs to what.
Maybe a collection should also hold a list of items and folders.
UI differentiation between personal folders and collection folders might lead to confusion though.
