When you press the evolve button, and the menu comes up, instead of having to click on the alien you want, assign a number to each species.
So if I press Q then 1 it would open the evolve menu then select dretch (if I was granger)
1 = dretch
2 = basalisk
3 = adv basalisk
4 = marauder
5 = adv marauder
6 = dragoon
7 = adv dragoon
8 = tyrant
As players learn these numbers they'll be able to select an evolution very quickly, even mid air while jumping <_< if they feel like it (lol, dretch drop off roof... tyrant lands on someone hahah. Maybe disable midair evolves if they're possible)
Same for the human armory. Except I think you'd have to use letters too since theres so much stuff in there :/
Edit, for human armory, maybe sub menus. (Weapons/Items or something)
And also, buying ammo should get ammo for everything you've got, not just whatever you have selected.
