Easily move date of a task
If I list tasks due within the next 7 days, it'd be great to be able to drag a task from one date to another. Instead, I have to click on the task, open up the calendar by clicking on the date, select the new date, and then finally select "save".
Also, having chosen the new date, the task remains within the previous date's entry. One has to actually refresh the screen in the browser to see the task listed under the new date.
