Is there a Calendar mod out there in which performs the following for 3.6.1?

Hello, I was wondering if by any chance there is mod out there in which allows someone to turn the Calendar link into a drop down menu with links to all the other Calendars accessible to them.

Also I would like to have a main general calendar in which puts all the events from the other calendars onto the General Calendar as well so that way people have the option to sort through the calendar events by a particular category so to speak.
