it would be nice to disable unusable buttons in base
it already works for the "new base" button -> (it gets black)
no soldiers -> disable soldiers
no crafts -> disable craft equip
no scientist -> disable research
no engineer -> disable manufacture
also possible but a little more complex:
no item/crafts/aliens/staff -> disable sell/transfer
no space left in base -> disable build new facilities
no storage/hangar/quarters/alien containment -> disable purchase
i sometime click on the wrong base to research stuff so i can likely avoid it
