Allow more project filters

When I look at the project page, I like the different filters like NEW and DEADLINE. Those are the two I look at the most. But I also want to sometimes see only projects I haven't already submitted to and sometimes I ONLY want to see those I"ve submitted to. I like what you have so far but just MORE. And perhaps make them additive like other website do? Like I want to see NEW projects that I've not already auditioned for before. Or Deadline ones that I HAVE. etc. Perhaps there are other tags people would want too
