Could it be made possible in a future patch to shift forces from left to right commitment boxes in a battle (until you press the engage button for the first time, of course)?
Its not pleasant to lose a big battle just because one didnt see it was a big battle, and has deployed all of ones troops to the left side (and loading a previous save produces different results, so cant really be used as a remedy).
I do understand it is not necessary to put any troops in a commited box in a small battle, but it is an intuitive thing to do and hard to give up on (at least for me...)
Cheers,
Filip
