What I did: Created a Calendar Event from a Note in a Project, then, in BusyCal, changed the time of the event.
What happened: In Agenda, the Note still showed the original time.
What I expected: That the changed time would sync back to Agenda
ALSO rather frustared that, when creating a Calendar Event, you have to enter the start/end times manually. Would help if you could advance the cursor to the next field with Tab, but you have to click each of the four fields. Very slow.
