I would like to see shortcut buttons for postponing tasks (maybe subtasks) to the next day, next week and next month, or some number of days informed by the user. I frequently have to move a task to the next day or postpone it to the next week, but it takes too long to open the details panel, click on the date, choose a day on the calendar and close the panel. It could be done with one or two clicks maximum by simply hovering an item an clicking one of the aforesaid options from a fade in menu/bar or selection the tasks and than one of these options from a fixed bar at the bottom.
It would just make my experience much nicer.

In addition I'd like to see a postponement option of 1 hour so that I get nagged until I actually do it!
I had asked (as others have) for editing multiple items, but this is even better. I wish I could give this all my votes.

I love this idea. It is probably my #1 favorite idea of those listed.
