I can not live without this awesome add-on!

However I have just identified that the reason of heavy slow-down (almost freeze, actually) of the "quick search" was this add-on.
It is most significant in a "saved search folder" (or "virtual folder").
It has got even more significant since TB31.
Hope it is root-caused and fixed soon.
