You could chain the tiles to feed plan and harvest.
Feed a1 a2 a3 ... etc then just press up to recall the command
The only pain was the up arrow also brought back the text than the command. 

Really nice game, loving the art style and enjoying playing it so far.

Couple of things, the viewport can shake constantly when trying to move the camera to the middle when a level is complete. 

Tier three isn't explained that well, you basically have build a network of pylons and ports so you can build the other buildings?

Menu is bugged in the advanced situations screen. Won't allow you to return to the main menu. Fun little game though!
