Some of our users suggested the following calendar functionality.
One meeting follows another, there is usally no time to get on time to the next meeting, because the last meeting with your Exec lasted till the very end, and you didn't want to get out off the room early...
There should be an Option or Cal. Pref. that adds an additional 5 or 10 Minutes to the TimeSlots of an Meeting (Availability) if a person accepts an invitation.
The Find Free Time Functionality would therefore not allow a meeting to last til 3pm and the next to start at 3pm, but at 3:05pm or 3:10pm
