While we're making UI suggestions:
In addition to that embark all, could we please get a toggle for the selector between armies and ships?
When I want to select a big group of units, I want to select the armies and move them somewhere, and then the ships and move them. But if I drag a group on screen, it always picks the armies. If I want the ships, I have to zoom in and pick each navy out to avoid any armies on the map. I want a toggle so I can pick which gets selected when I drag.
I agree!
I've heard of the following work-around, though I can't recall if I've actually used it: Select one ship. Then hold SHIFT while you drag a box around all your units. You'll get the ships instead of the armies.
