I'm not sure anymore... I mean I understand the play style isn't for everyone, and I wouldn't mind an option for more hassle free play for those who choose the option, but having played quite a bit, the gathering of bio mass can easily be done while waiting for some extra resources being produced. It actually keeps you busy and possibly sends you out exploring a bit. Also, Constructors only use up 4 mw, 1 bio burner will feed a refining setup, and you can always make space. Personally, I always make the bio mass myself, stick it in a container and brew biofuel from it. Only costs 1 4mw constructor and 2 containers. Build a personal storage close. Add 1 constructor and store the leaves wood/ wood then switch the resource in container / constructor. cost 8 mw, choose a central location where you pass by a lot, next to a craft bench. There's plenty of ways to handle the prob.
