My two penneth. From a Day 1, calendars feature extensively throughout my flagship app. And I'm now introducing scheduler operations as part of a project management module.
Calendars are by far and away the most efficient way of handling time based data sets. The slicker and more robust this part of AwareIM can be - the better.
As a Mac user, I have to say, the ability to export calendar entries as iCal files is a superb feature. On Mac's (incl iPad) it opens up my calendar, gives me the option to select which of my calendars to use and the inserts the entry as I watch.
A GREAT REFINEMENT (in my opinion) would be have the same export button on the edit form that pops up when a user selects a calendar entry. This would save a few clicks whilst a user drills down from a month view to a day view, and allow the user to select just one event to transfer into their own calendars.
