Additional Filter criteria in Bridge

It woiuld be great if the list of things one could filter on in Bidge included Type, in addition to star ratings. I often want to display and work with only, e.g. PSD files. Sure I can sort on Type, but when I am scanning through in full screen mode, it's easy to circle through into another Type.

Even better would being able to filter on more than one criteria, such as "show all PSD files rated 2 stars and above"
