For duplicate events: show all calendars they occur in
The option 'filter duplicate events' is a godsend, thank you! I have one small issue with it: when multiple events are combined in this way, it doesn't seem possible to tell which calendars have a matching event without going to settings and disabling the option. It would be nice if you could see which calendars have this event in event details.
Yes! Maybe even using all of their colors as well. Striped? :)
