In prior versions of Paperless, dragging an item from the inbox to a collection removed it from the inbox. In version 3, dragging an item to a collection adds the item to the collection, but leaves the item in the inbox. Deleting the item from the inbox, deletes the item everywhere. I use my inbox as an "inbox" for things to be edited and filed in a collection. I suspect most users use it that way. The inbox will be useless for this purpose if everything must remain in the inbox to avoid deleting it from the collections. It will eventually be just another Everything location. Can you elaborate?
Great question. Many users complained that they didn’t want the file removed from the inBox so they could drag it to multiple locations. That is the purpose of the done button in the detail pane. We will most likely be adding a preference in the next update to allow you to control this behavior.
