2 main cases that creates unreferenced documents today

(the rest are errors)

Case 1 (to be solved):

I got a document card in the parent and I delete it manually (erase). This do not delete the document, but keeps it there in unreferenced.
Right now the path keeps the same ( the origin)

Solution idea: We notify the user with options: "By removing this card you are not deleting the document but making it invisible, what you want to do? A) Delete document B) Move it to no location in document browser...

We create this "no location" area in the sidebar. User can drag and drop and move to any location, including the original one.

Or we create a folder inside the parent in the sidebar with this documents that are hidden.

Concept: "Bring back to location"

Case 2 (to be solved and depends on solution for case 1):

I do the erase cards in a document, they go to unreferenced BUT when I create a query block taking this document it will take these documents I deleted as well. This is weird because user wanted to not have those documents in the parent.
