I know, there's no easy solution. The xF version looks great, but it also adds 2 kilobytes of HTML, so I thought about doing it in Ajax, but it requires refactoring the search template, and I don't really have time for this this week (I think.) (Then again maybe I'll do it in ten minutes..)
I originally wanted to do the mini-menu popup, and only on focus, but failed on both accounts, so I took the easy way out, ah ah...
Warm search box is also broken, BTW, because of the difference in alignment (left sidebar) and color (left sidebar and bottom sidebar.)
I'll need to fix that...
