I am very curious, is there an effort to focus on speeding up the UI, or decoupling UI responsiveness from the pages/plugins active at the time?

I want to know what search engine you speak of.

Anyway, somebody gave me a cube to solve once. After about 15 or 20 minutes it dawned on me that I had an impossible cube. Somebody who thinks they're moving closer to the solution by swapping stickers can do something like put the white sticker on a corner cubie with the blue sticker, not realizing that white and blue are always on opposite sides.
