[claus]

But these are subscribed calendar entries are CALENDAR ENTRIES and *no* ToDos/Reminders. Thats something different! I am not allowed to make any changes. I just had a short look at it, but I think its not a solution that works well for me.
The old workflow was much more flexible, I could define an Reminder in BusyCal as "Done" and OF got the info and checked it as "Done" (well, I almost sure it was like this).
