As a user, I'd like to see the ability to have additional filter options to the "Assigned to Me" dashboard gadget, similar to the Filter options found on other gadgets, such as Activity Streams. 

This way, for a specific dashboard, I can use the "Assigned to Me" dashboard gadget to only show a specific Issue Type (i.e. Bugs only, Test Cases only) instead of seeing everything that is Assigned to Me. Or only see items from a specific Project, instead of from all projects.
