I guess these are feature requests, but involve the ai, so ill put it here.
Flee AI - If enemy unit is within line of sight of the builder, it flees a general direction from the enemy automatically if its set by player.
Explore AI - Unit randomly selects an area in the map, and goes to it if accesable, so its easier to send 50 zippers or finks out to scout to see how it dies and look at enemy expansion.
Maybe a few others, just some good ideas like usual
