Could the minimum transition time for a workflow (currently 5 minutes) be lowered? We sometimes need to pass a document through a state to send a notification, but then need to move the document along through the workflow for further action. If a user expects to be able to do something but can't in this 5 minute window, that can be confusing.
Ability to have workflows appear nested in the administration - for example if a document from initial state goes to state X based on metadata A, or state Y based on metadata B and then through an approval workflow, this appears as a long and confusing list of states in the workflow menu. (see screenshot)
Improved transitions in workflows - Things like if...and statements (currently would have to run document through multiple states to achieve this) and ability to use more fields (eg document creator)
