I didn't want to submit this as a link, I just wanted your opinion as to if this is useful to you all:

This helped me find numerous jobs on CL. I don't have all of CL in there because it was a lot of work just getting what is currently supported. This is just for the U.S. This is a not-for-profit tool.
I had to click lots of stuff to get it to select only my city.
I don't like the "window" tabs much. Maybe it would work better extracting text & attributes then letting you expand the entry in place, or perhaps by flagging items of interest then generating a report.
It would also be cool if it allowed more detailed filtering than is already supported by CL.
I'm a networker so CL isn't really that useful to me personally, but lots of people rely on it for job searches and improved usability / accessibility could be a significant boon there.
