Can add multiple calendar widgets – each of them set to different categories (or All Categories).
The tooltip on the per-day links shows only post titles from that category, and when you click on the calendar link to bring up the day archive of posts, only posts from that category are shown.

Calendar Category

Un-registers the default Calendar widget, and registers a new one which supports showing only those posts in certain (or all) categories.
