As the name suggests, a sort of drop down list of all the slots on a ships where one can click the name of the weapon and a line goes from the list TO the implied weapon
Slots can be "named" or tied to a group name
(for example a group named starboard, wich contains all starboard facing weapons)
Clicking the weapon's name again lets you change the weapon
and next to the weapons names you have numbers you can click to assign to a weapon group
this is mostly motivated for mods that try to have a bit more visual flair by having custom effects for their weapons (Arma Armatura's mech arms for example) or ships with the ever popular "invisible weapon" trick
