Right now the only way to sort in the Document System is A to Z or Z to A based on the document name.
Please allow the user to sort by document variable.
The only way to create Sets is manual.
Please allow the creation of Smart Sets (like the Smart Folders that MacOS has had since 2002 or so) where the user can select a set of criteria for the documents to be included in the set.
