Hello there!
It just came to my mind that it would be amazing if you could drag and drop more stuff into empty weapon slots. Dragging a drone categorie into an empty slot besides the energy donut could result in either a new button that does launch them or even multiple new items like call drones, drone attack and so on so you could activate them with a mouse click or with the F keys like weapons and other active modules.
Then you could conviniently activate all of your stuff on a target from there instead of tediously using the drone window.
