Dashboard filter

Interesting request in from one of my power users - she wants to be able to display all of her subscribed calendars on her Calendar page, but on the dashboard widget, wants to be able to filter out some of her less-used calendars and keep just the key ones.

As an examples, she is subscribed to calendars that show events, staff leave, birthdays, holidays, etc., but just wants the events on her dashboard as they are most key to triggers in her daily work.

This is obviously a power user case, but it seems to make a lot of sense to me. I'd also use it.
