For #3:
Yeah, the AI should offer a preset of commands. You press a button and all commanders tagged as searches move somewhere where they can search. The automatic set movement should have a different coloured arrow and its own "n"-key to cycle throught them.
Really, commanders should have 1-3 tag boxes and for each tag there should be a key for cycling through them (i.e. cycling through searchers, forgers,etc. - with the tag being idependent to their current action, so that you can find four forgers the next turn again), as well as a key which removes a commander from the current cycle just for the time being (i.e. unless the turn is saved and reloaded later). I hate it to come back to commanders by an 'n'-key that I had already considered to leave as they are...
