When working down my inbox quickly, I want to be able to plan a task before I project it (and vice versa). I don't want to have to think about the order in which I type commands. The current behavior will remove the task from the inbox as soon as I plan it so I have to remember to do everything first (projects, due date) else I then have to go chase it down (which breaks my flow) or leave it without a project assigned to it (which hurts my organization).
