Just small stuff that can be fixed in a moment
1. The labels of objects should be invisible when they are behind some other object. Right now you can see the labels (the names) of the objects through another object, and it is kind of annoying.
2. In the add list, make the images of planets/stars/etc have a transparent background. It would look a thousand times better. Use a PNG file I guess.
3. When the add list is opened, clicking the "add" button again won't close the window.
4. Organize the list of simulations. I'm pretty sure you can get rid of a lot of test simulations that are taking up space.
5. Shorten some of the trails. In the solar system sim, for example, all those minor objects with huge trails make the simulation look dirty. The planets should have a more visible trail than all the minor insignificant objects
6. A real time button in the timestep controls
Gabriel's got some good ideas here.
I'd like to add the following:
1. Fix Wolf 359. It's not a brown dwarf. It's a RED dwarf.
2. Get rid of the DDouble CCapitAAls bug (or am I the only one experiencing this)
3. There seems to be a memory leak. The program gradually consumes all available memory on my system if left running for hours (as in more than 24 to 36). I have some long-running simulations I would really like to not have to cut short to avoid these annoying crashes and resultant loss of data. I am running it on a stock Dell Optiplex with an i5 at 3.4 GHz and an nVidia 730. RAM is a roomy 16 GB.
4. It would be great if we could have more than one "pop-out" graph at the same time.
5. Could Pop-Out Graphs be made so that they could be iconized, or rolled up into their title bar? It's a pain to have to move the graph window out of the way to get at the save dialog or make an adjustment to the running simulation.
6. Adding moons and getting them to stay in orbit around their primaries is still almost impossible. For example, placing a moon in orbit around an earthlike world orbiting an M0V 0.5 solar mass red dwarf is not possible--either I have to move the planet too far out from its sun to support life, or if I leave the world close enough to the star for (humanoid) life to survive, the moon gets yanked out of orbit and ends up orbiting the star, rather than the planet. This has lead to several rather embarrassing collisions....
7. When a star is seen through the atmosphere of a planet (looking past the edge of the planet at its sun), the portion of the star obscured by the atmosphere turns black. This needs to be corrected.
I think Gabriel got my other points, so that's it for now!
