Limiting the speed at which a unit could turn around would make units in the air, and perhaps some on the ground, a little more realistic. If the limitation is implemented, it should have a setting to tell whether the unit should be moving at the moving skill's speed during the turn, or if it should just turn slowly on the spot (i.e. if the unit were a tank).
It would also be nice to be able to force a unit to have to keep moving no matter what it's doing at the time (though this might cause some issues with harvesting and healing...but I suppose that the unit could circle within range of the target of its current command, or something), somehow forcing it to circle (or, perhaps, the path could be programmed with something like Logo) around the point it is idling.
