My small wishes for the tactical combat

I enjoy the tactical combat and like FE finally very much.

But I would like a few options for the tactical combat to be able to switch to AI without regret it.

1 I would like a to select between some mana usage states:

a. Burn mana for all use able spells.

b. Mana for healing only allowed, e.g. target fall below 50% health.

c. No mana usage allowed.

2. I would like to have a button for every unit, so this unit try to stay away from melee combat, maybe 5 squares.
