More stats!

It would be fun to be able to see:

• in a calendar view, on which days did I complete workouts?
• How long did each workout take? (Time from tapping start workout to tapping finish workout)
• An average of the last point with trends.. are my workouts taking longer now than when I started?
• Rest stats: do I follow the rest timer in Dr. Muscle exactly? Do I rest longer between exercises? Shorter?
• Length each exercise took + trends

There are tons of possibilities here and the list above is not exhaustive.
