I like the suggestion to attach cost to different dev lab slots, but I want it to be optional. Idea itself seems to be good, logical etc., but I personally don't want to micromanage this aspect of the game - I wish that others, who might want to get involved in even more finance tinkering, to have that opportunity. I am absolutely hooked on this new development lab but I would be pretty upset, if I am forced to deal with it's possible financial aspect. Great idea, just make it optional. Please.
