Thanks for the hint, I’ve added it to the roadmap for DAVx⁵:
As you can see, there are a lot of possible enhancements, so maybe this will take while…
i’m using mostly shared calendars, so it would be nice to have an option to enable notifications about synced items. maybe even in a configurable verbosity e.g.:
so you know that/when other people modify the shared calendar.
i’m not sure if it’s possible to detect which item a user clicked on in the notification, but there could be an action opening the clicked event in calendar. or just the first one.
