Well, until my voice returns, the wife doesn't mind me coding in silence here (laryngitas).
The new button queuing method should make button macros much more reliable, especially when feeding stuff to the player software. Also, there should be less "lag time" between when a button is pressed and when the player sees it, versus previous versions of Hijack.
So, yes Tony, I think it oughta help all around.
The only downside I can see is that the Hijack button queue is only large enough to hold 24 press/release pairs at a time. This can be changed if it's a problem.
Cheers
