What is the enhancement in mind? How should it look and feel?
AuctionLite is superior to the default auction interface in almost all ways, but seems woefully lacking in one area: filtering searches.  I can find no way to just search for glyphs for Shaman, for example.  The default interface's implementation is obviously fairly wasteful of screen real estate, but could another way to duplicate that functionality be found?

Perhaps you could add an extra line under the search box for a dropdown for categories, another dropdown for subcategories of the selected category, two fields for item level, and a box for "Usable item".  Perhaps this extra space could expand downwards from the main panel when hit an expand arrow?  These are all very useful filters for me, and I don't think they'd have to take up much space, or introduce unnecessary complexity.

Please provide any additional information below.
I recognize that this is a tall order, and I'm not likely to see this (anytime soon).  I just wanted to throw in my $0.02, at least.  Good luck, and thanks for a great mod so far!
