I believe one feature that would transform Workflows into an even greater Redtail tool would be being able to upload/store documents and/or other resource/source/artifact files into individual Workflow Tasks. This added feature would, in my opinion, make a Workflow way more of a hub for office activities. If a specific document/file is in fact needed for a Task or is the product of a Task upon completion, being able to add it to a Task or, more broadly, a Step makes sense.
