I would like to be able to adjust the orientation of units. For example, I let a bunch of archers march on a hill, but I can not tell them in which direction they should look.
In Praetorians, an older PC game, it was possible to keep the right mouse button pressed and draw a yellow arrow to the direction you wanted to let your troops look.
In my archer example this would work like the following: I select my archers, then I would press the right button to let them walk to the hill. However, I keep the right mouse button pressed and draw an arrow in the direction my archer should look.
This would be really helpful for units which are in a formation. In Praetorians most units have been always in formation.
