It would be helpfull if you could edit standard options on card inline in the plan activity. Today when you mouse over a card from within the plan activity, you get a popup where you can see the details on the card, but it would be nice to be able to edit the basic details directly in that popup, such as assignee, due date and category. It's very time comsuming having to first open the card up in the board view, edit the details and then return to plan view.

When you open an activity and then want to edit details in a card you simply click on it. The detail pane of that card will open in the same area and make it possible for you to edit. When you are done you can simply close the card detail pane and you will be back to the activity detail pane.
