MJ works beautifully, after 1.3 update, without a hitch. But I would like MJ functionality automatic, without adding a part, but is part of every command module. The mod "MechJeb Embedded Universal" by Dennis6492 is what I was using prior to 1.3, and it added MJ to every command pod and was amazing. And removed the career mode tree buys. From what I have read, it is just a .CFG file, to be caught by ModuleManager, to edit the parts/functionality during loading without hacking sarbian's hard work. I found numerous posts from several years ago about the same issue, and saw many suggestions to make edits to the MJ .CFG files. I have tried those, and as it sits now the tech tree us completely unlocked, but still missing the automatic MJ connection without the part.
