what use do you have in mind for such feature?
The primary reason is the one I gave initially - pause, issue positioning orders, then unpause and have everyone go where I've told them to. It's really, really awkward when trying to set up an encounter to have to ungroup, then one-by-one have people slink off to where I want them. I think of pause like a huddle. "Gale, over by those rocks, Asterion, up on that bluff there, Lae, after the initial volley, you just charge up the middle, I'll pick off the weakened ones... 1, 2, 3, break!" Then when everyone is in position, pause, give everyone an attack target, and unpause for simultaneous fire
