LeechmasterB: Yes, you noticed that there are still some gaps at the bottom of the interface where the buttons are. I'm still gonna add five more actions (build stairs/ramp, dig diagonally up, dig diagonally down, climb, and parachute). yeah, you can't abort an action (just like the original lemmings, i think) but you can re-assign. If you make one "pipol" into a digger, you can click him again with another action and he will do that action. The only action that cannot be re-assigned is the "blocker." You gotta blow him up if you want to get rid of him.
