It would be useful if by moving the mouse over a progress bar there would be a tooltip displaying some basic info of the given task.
E.g. I have a task that says "23 weeks remaining (Mar 13, 2015)". It would be useful if a mouseover tooltip would also tell me:
- starting date/time
- ending date/time
- time (weeks, days, workdays) elapsed since start time
- time (weeks, days, workdays) remaining
