At my current science level getting into orbit and de-orbiting uses everything Ive got, especially if i'm actually trying to take anything up with me. It looks like Im just going to have to drastically scale back on my goals. Also, am I crazy or can you stop and lower your thrust from orbit view, but not increase it? When im trying to tweak my orbit, in the rare cases when I actually have the means to do so.. I can be in orbit view and turn my engine off, but I cant turn it back on, I have to switch to staging view, turn it on then switch back to orbit view.
