Calendar entry should show who is invited optionally / required
I want to see who is required in a meeting and who is optionally invited.
In particular, I would like to see if I am required in the meeting or only optional.
In the invitation (the e-mail) it is visible whether I am required or only optional. In the calendar entry itself, however, I only see who has confirmed or canceled.
Especially if i only confirm tentative, it is important for me to see later whether the organizer has invited me as required or only optional.
