Subject says it all. The current implementation of calendars on the dashboard doesn't work for us because we draw from multiple folders and spaces, not just one. In a perfect world I'd like to build a calendar drawing from the entire account, and then use the parameters to dial in exactly what I'm looking for. My only solution now is to create dozens of calendar widgets.
I get that I can achieve this with the Calendar tool, but I'd like to be able to build and share a single dashboard instead of a dashboard AND a separate calendar.
