Long-term user of the "Maneuver Node Improvement" plugin here. Thought I'd check this out as I read the thread a few weeks ago and have been meaning to evaluate it. A new KSP version is always a good opportunity to try out alternatives! Initial impressions based on about 20 minutes of play: Love the ability to switch between nodes. I don't often use multiple nodes due to the accumulated error in their execution. However, I do plot multiple maneuvers as part of an exploratory flight plan when slingshotting etc, and it's a neat trick to be able to quickly edit them and see knock-on effects. I'm actually finding that I'm attempting more complicated maneuvers now that I can simulate them with finer control. Love the additional data readouts of ejection angle and dV. I would also second the suggestion for accumulated dV calculations (if possible). The apoapsis/periapsis readouts are an absolute godsend. No more fiddling around trying to click the apo/peri points to get permanent readouts. Although the increment is global, rather than per axis, I actually think this is more intuitive to use. I also quite like the fact that it restricts itself to map view. Great stuff, man!
