I've been toying with the idea. I've also been toying with the idea of only allowing units or building to be put into a production queue if there is a general present (and only then can you change tax rate) but I ran into a couple problems with this. First it requires more micromanagement of generals than I like to do. Second, it doesn't make sence that a General couldn't get someone to carry instructions for him back to a castle over a two year period of time.

For the autocalc, I've tried it but I've gotten a little bored with it. There are too many fun fight that happen to not have a general present to skip.
