improve the library search mechanism
I find it incredibly difficult to search the library for questions. Some possible improvements:
1) Allow for wildcard keyword searches: "kinematics" would match both "1d kinematics" and "kinematics 1D" (and a number of others) so that I don't have to repeatedly search and click to look through the various keywords
2) Instead of just a few words from the beginning of the question, allow toggling of image display (often seeing what graphs are included would more quickly identify a useful question than a few words). One vision of how this might work -- do a google search for "block on incline" and across the top are several image search results. You could do the same thing
3) Allow sorting of results -- by popularity (how many uses), by difficulty (will become more useful as more questions have been used), by date added. Also allow grouping of results -- I don't necessarily want to choose one question format but grouping by format would be helpful.
4) Similarly, rather than allowing selection of just one question format, multiple formats should be able to be chosen, and most useful, a selection of "all auto-gradeable formats"
5) To improve tagging, it would be nice if there were a text box to the side of the question when I went to view it that I could quickly add some tags to. Improving community effort relies on making it easy for the community to help; I would be happy to add some tags to questions that I open for a moment to see if they are something I'm interested in if there were a simple way to do it.
There is so much content and it is so hard to find. I would use all of my votes on this if I could.

In addition to wildcards I suggest full fledged regular expression search. Seems strange that you didn't implement that already since you do have this feature for questions evaluation.
