It was cool when Tracker search was barely integrated anywhere. Nowadays, it's nothing but an aging showcase app (eg. was conceived in the gtk2 days and barely ported to gtk3, and it shows everywhere). If you want a modern and capable search UI, try Nautilus. If you are outraged that tracker-needle is gone and ended up here, by all means be my guest, reset to the parent of this commit and take it out of tree. If you join #tracker I'll gladly give you advise on how could it be brought up-to-date. But our hands are full, sorry, we leave cool UIs to others.
