The new calendar is fun, though now that the stake has created their calendars and added events, the view gets quite crowded with our ward items listed, too.
I know that I can un-check any box for any calendar items I don't wish to view via the "Subscribed Calendars" box on the right, however, I now have 25 calendars listed and don't want to have to un-check 14 Stake calendars to only see my 11 ward calendars, then re-check them to view them all again. Call me lazy...

How about separating the view of "Subscribed Calendars" into two separate boxes for ward and stake calendars? Each could have one "master" check box to un-check all calendars listed in that box, whether ward or stake. That way we could view only our ward items at one click of the mouse, or only the stake items, then both.
I would think this would be possible as the ward and stake calendars are separated on the "Select Subscriptions" page.
Just a thought...
