Hi guys, I found out KSP just a week ago but have been hooked since then. Watched a lot of tutorials and managed to get some missions going. Now I would like to start doing things like NASA/ESA are doing, e.g. build a kerbal version of the ISS (or a similar large structure station), create a satellite, put it into a cargo hold and deploy on orbit (I don't like the tutorials/videos that just put the sat thing on top of the rocket and have it wobble all the way through the atmosphere - that's not very realistic), go to the moons, planets etc. What would you consider the absolute must have plugin/add-ons for these things? I already have MechJeb and love it (once I figured out how to the the burns I don't wanna spent too much time doing them manually). Thank you
