Whats the matter with Galactic Map Window lagginess?
The left side menu flickers and feels like it reloads all the data for every object seen in the view when you pan around even the slightest amount.
Main Tactical view has small fraction of same behaviour.

I'd like to be able to project the position of a system body (at an arbitrary point in the future), given its orbital parameters and current location.

Would that be a straightforward formula you could share?

...It's a few hundred lines of code...

I suspected that might be the case.

Am I correct in recalling that orbiting bodies sweep their orbital area at a constant rate over time?
And if that is correct, is that how Aurora implements it?
If so, I can probably work out the general case formula from there.
(Not, like, over a lunch break. But eventually.)

Orbital Speed = Math.Sqrt((2 / DistanceToParent) - (1 / OrbitalDistance));

I've noticed that my officers are retiring at age 32-33. Should there be a kind of military administrative structure to provide them with jobs as they age? A fleet staff structure or a general staff for ground commanders? If the answer is "yes," how would I create such a structure?

I don't have any warships, and the only ground unit I have is the "1st Infantry Regiment." I don't have any alien invasions or NPRs enabled in this game. It's my 7th restart.

You can assign commanders to academies, via the commanders screen. If you have lots of scattered academies that can give them something to do.

You can also create a naval command structure using the Naval Organisation screen.
Some people use this to create a civilian command structure as well, here is a post showing that:

The industral, logistics and survey admin types will provide useful bonuses even in an entirely peaceful game.

If you have no navy or army why would any officers stay in the service?
Unemployed officers tend to retire faster than employed officers. It is usually a good idea to use your starting research points to develop some tech, then design some ships and spawn them using your starting points for troops and ships.That way you have a navy (military or commercial) and army and that means your officers have meaning. Also you can actually do things and have fun

I have a couple of survey ships, a sorium harvester and a couple of freighters. I have not built a military because I'm not very interested in the military side of the game, at least not until I understand the basics of building up an economy.

Your wording of Keplar's 2nd law is not quite correct, but I expect you know what you meant.
"An imaginary line drawn from the center of the [star] to the center of the planet will sweep out equal areas in equal intervals of time"

The question is whether Steve has coded Aurora to account for gravitational interactions from other bodies.

It's not really straightforward due to it being an eccentric orbit, plus planets move at different speeds at different points of that eccentric orbit, and planets can potentially orbit a star that orbits a second star, that orbits a third star.

It's a few hundred lines of code, including some parts you wouldn't need, such as moons and environmental changes, but I would need to figure out which parts. Essentially, I calculate the movement as degrees of arc, based on body speed and time elapsed, then calculate the distance of the planet at that point of the arc, primarily using trigonometry, although some conversions are needed for the way C# handles it. If you orbit something that orbits something else, etc. you need to calculate everything in order.

I just received a notification from an NPR that they no longer consider us hostile, and "we now have a neutral relationship."

If I set them to neutral, do they receive a similar notification?
Do they receive a notification when I set them to hostile?

Your setting is for your internal purposes. Right now they consider you neutral and will act on that basis. They won't know whether you consider them to be neutral or hostile until you open fire.
