psorek, that question goes to me, I assume? Or to Peter?
I was thinking of writing a script when I had to build the G96 killgem (which wasn't too much fun), but didn't do it yet. My coding intelligence is rather restricted. I definitively will/would, if I should continue to play or do another run like that. For the moment, as endurance took so long, I'm a little tired of the game.
Do you use supergemming-scripts? If I would build one I would share it, in case anybody should be interested. It would certainly not be very elegant, though, as I don't have any coding skills. You could certainly do it better.
There's a chance the newer 'demo' version is crippled, but Axife Mouse Recorder is a program I use to record and play back mouse/keyboard movements, clicks, and keypress.
