You can now set the title a copied event carries, per calendar, with a template. By default a copy is named after the calendar it came from, which keeps the original title private but tells you little when three calendars feed the same destination.
The template takes plain text plus two placeholders: the original event's name and the name of its calendar. "Work — {{calendar_name}}" labels every copy so you recognise it at a glance, and "{{event_name}}" passes the real title through for a calendar where privacy is not a concern.
Because the template is set per calendar, one connection can pass full titles through while another shows only a block. A common setup keeps your own calendars readable and reduces the ones other people see to busy time.
What a copied event shows covers the title, description and location settings.
