One thing I’ve noticed in campaign mode is that adding ships to a fleet can be a pain when trying to make sure that the new ships you built (or captured) have the same orders as the fleet. I’m suggesting a clone or copy orders button.
The button would work as follows:
In the fleet deployment screen, select the ship, or ships, that you want to modify the orders of.
Click the copy orders button
Select the ship who has the orders you to apply to the ship(s) you have selected in a dialog box
Click OK. This applies the orders from the original ship to all selected ships.
Edit: I noticed that when you select a large group of ships where some have the default orders and others have customized orders, it will show the orders of a ship that have been updated. Perhaps having an option to apply displayed orders to all selected ships might be easier to code.
