You should be specific, Velo. Specific things I can think of offhand: We need to help Calclavia get good steam ratio numbers. DoctorOr was looking at this. Steel creation from Mekanism can muck with things. It'd be great if we could easily introduce lossiness to the Mekanism power conversion. Sometimes it's not good that it's so efficient. It'd be great if MFFS had some smarts about other mods. Like for example, a config option for portable holes.
