I got all the way to the satellite before realizing that you needed RCS *tanks* in addition to just the thrusters*. An obvious mistake in hindsight, but for me who was just learning the game and had never built an RCS-capable rocket, it was frustrating to reach for that RCS button and not have it there.

I'd love to see this, but it has to be very unobstrusive (because it isn't really the important information), which is a little difficult because you can have apoapsis, encounter and other such infos basically anywhere on the screen.

I've played KSP for ages and i know how to get around with orbital mechanics, but I cant seem to figure out a good way to make encounters with planets execpt the ones that are in a perfectly circular orbit. I would be so many times easier and allow much more efficient transfers if we had an encounter shown like in KSP. Also conics would be nice (so you can see your trajectory even out of the current sphere of influence).
