I just tried the calendar in 3.2 and right away I'm finding:
* All day events that span multiple days only show up on the starting day.
* Changing the end date on an all day event creates a duplicate event.
* Apparently no way to sort events by tag or anything else. I see the tags thing on the right, but clicking a tag doesn't do anything.
* No recurring events.
Is this feature considered usable? Perhaps I'm missing something. What kind of work is it getting… is a feature updating coming soon?
