In the upper right, the day start and end are based on the lowest and highest values based on any of the timelines. At times, there are items in my outlook calendar timeline which aren't dictating my actual day working (such as a reminder, or an out of town trip, or PTO). It would be nice to choose what timeline dictates this feedback information. For instance, I would want it to represent my Tags as my outlook calendar might not have accurate working time.
