Members advanced filters vs member search

With the expansion of the search system I would have thought that "Show advanced filters" would have been transplanted there. If the plan is to keep the advanced filters... can this be re-designed a bit to use space a little better? It's really large... and to be honest, I've never really liked the way it looked because it doesn't make good use of space. Could it be done in such a way that allowed the "custom fields" to use both sides of the column?
