May be that programming is slightly different for platforms. I'm able to star events and it will list multiple events in the same time slots on the app's internal calendar. I have not tried dropping multiple events in to my phone's calendar. iPhone 4 utilizing latest IOS. I like hard copies for backup, however, I like the alternative e-version, but both for different reasons. At the conclusion of con (blasphemy for even thinking about it before it starts) I'm sure DC staff would love to have input on how not only the app can be improved (or what was sufficient) but how the entire experience was for everyone.
