What I would like to see:
More wiring colors
Inverters(invert power so input would be on and output would be off; and vice-versa)
Make other statues do stuff
New triggers, including a time-based trigger
More clocks - 0.5 seconds, 0.25 seconds, 0.1 seconds, 10 seconds, 30...
Only 38 hours, 30 minutes left! I can't wait!
Once it comes out, I'm going to do a regular mode LP, followed by an expert mode LP. After both of those, on to making over complicated machines that look cool, and do something useful on top of it.
