Is it possible to have calendar events open in BusyCal instead of either Calendar or Fantastical? (This was possible, with some editing, before the native calendar widget.)
@Andreas_Hegenberg would need to add this as an option to the calendar widget; I would be happy to support it in GC's UI as an alternate calendar selection if he does so!
Fantastical went to subscriptions. Just ditched the app and got BusyCal.
