Logging time

It would be awesome if there were an option to view the amount of time logged on a given task. If I could go from looking at a task in the Tasks and Milestones view and click a button to see how much time has been logged on any task (over all time, or over a given date range), that would be very helpful.

Maybe this option exists, but if so, I haven't been able to find it =P
