Simplicity is the key. Tags and labels may make it heavy and overwhelming. Syncing with Google Calendar sounds promising, but I like the idea of exporting to .ics so that it would cover more applications. (though I do love GoogleCal)
I've also considered the different colors idea, and this might be implemented if I decide to build something like a comparator of schedules.

Thanks a lot for your feedback.
