So i downloaded the newest ver. and started a new game using the career mode. interesting to say the least. I did download Mechjeb.. Whatever was the newest and it's odd it's not like it used to be where you just pick how high you want your orbit to be and let it do it's thing. In face there nothing at all like that one there.
Yeah, there is. I am guessing you're playing career mode? In that case mechjeb functionality increases as you go down the tech tree.
Try sandbox mode to see everything it can do.
