Wouldn't miss it for the world!

Why can I subscribe to events? But not accept?

Yeah, the upper-right action thing is a little weird since we don't use it in other applications, but it has felt OK to me once I kind of got used to it / continued being too lazy to change it.

The alert poped up just now (5pm, end-of-day), but this was a whole-day event! We missed the whole thing!

Let's try again in another couple of years, maybe the notification system will select a more appropriate start time for all-day events by then!
