Close the order menu once it has been clicked

Add label to the arrow to show the order type, and change what it says depending on what it will do (e.g. join / reinforce / attack etc.)

Not sure what you mean, currently first you place arrow, then select what to do.

Ah true, however the original point still stands: closing the original menu after selecting an option. In this case the other issue relating to showing an appropriate order name is even easier, and we can explicitly say the target of the order as well so player is sure its working correctly.
