Plot points on orbital path to simulate craft

[Bobe]

I recently gave RemoteTech another go (a proper go this time), and I found it unnecessarily frustrating trying to position the satellites relative to each other. I know they don't have to be exactly equidistant, but I like to be as perfect as possible.

What I'm proposing is a simple (I believe) tool that would allow you to set a target and then right click anywhere along that craft's orbital path to plot a point. This point would emulate the orbital parameters of the target craft at this point, meaning the point would orbit around at the same velocity as the target craft at any given position. This would allow you to then rendezvous with this plot point rather than an arbitrary distance ahead or behind the target craft, which is often difficult to do with precision, especially when the maneuver node is shaking. This ties into another request I have: Maneuver Planner Interface Overhaul.

In addition to manually adding points, some sort of preset configurations would be nice. So say you set the target, you could then right click the target (or have a separate UI window, whichever works best) where you can select either a degree value for a single point. So say you select "180°", this would plot a point on the opposite side of the orbital path to the target. Similarly "90°", "270°" or even a manually entered whole number could be used.

Or you could input a number of points to plot at equal angles from the barycenter, similar to the symmetry duplication in the VAB. This would have come in handy when I was trying to launch six equidistant LKO satellites. I managed to get them roughly in a hexagonal arrangement, but it could have been a lot more precise and far easier with a tool like this.

I had the same thought and I think it's the FinePrint mod that adds orbit lines - just not a fake (or set of fake) targets that you could set as target. Was able to get a decent constellation by resorting to math and Mechjeb info displays but this would also be helpful when the satellites eventually drift off target (or I fat finger the wrong key during a burn).
