It would be nice to have more options for how calendar events appear. For example athletic events that come from On Campus have the team name as the event title and then again as team name vs opponent name. At first glance the event appears to be in the calendar twice. Being able to set the "team name vs opponent name" as the event title would be a preferred view.
That said, it would not necessarily be ideal for all events so the granularity to set it for specific event types, event categories or maybe event sources would be very helpful.
Additionally, it would be nice to include the "public" calendar events from On Message that do not belong to any particular group in On Campus on individual calendars as a filter option, that is show/hide events from the public calendar on my personal calendar in On Capmus.
