I’d love to see an order which gives players the option to set weapon targetting priority based on weapon type for a ship. Actually, setting priorities isnt required, just a checkbox to enable/disable targetting of each class of ship by that weapon type.
Create Order -> Weapon Targetting -> Add Order
Select weapon type from a list of those present on the selected ship(s)
Check/Uncheck boxes for fighter/frigate/cruiser to enable/disable targetting of that ship class
Create a cruiser with a mix of weapons. Leave ship targetting priorities at default, then add a weapon targetting order which stops torpedoes and heavy missiles from being fired at fighters (actually that might be multiple orders, one for each weapon type). This ship will move and engage enemies as normal, but wont waste shots on things it cant hit with weapons it cant hit them with.
Alternatively, disable all targetting of fighters by deleting the default ship prioritisation order, then add a separate order for suitable beam weapons which re-enables targetting of fighters. This ship wouldnt move towards or engage fighters, but suitable anti-fighter weapons would still fire at them when within range.
