I would love to see a button or single command that takes off the project and context labels resulting in the item back to my inbox for renegotiation.
Back in Windows (Net Centrics Outlook Add-in) days this was one of my favorite and often used features.
The iOS apps make it so easy to strip off the project and context labels but OF2 is almost impossible. Dragging things to the Inbox tab can result in some very strange outcomes.
