One big change (for a small utility) is the way it handles typing your command. QS would “forget” if you paused for, roughly 4 seconds. GQS doesn’t forget, in the same way gnome-do doesn’t forget. It felt clumsy at first, but after the “what will QS ‘guess’ I’m trying to type” coolness factor dies down, I find I prefer the memory permanence. Sometimes eye-candy can slow down pragmatism.
