Hello! Chris, I am the seaman that write you some time ago about the convenience of put the permanent "real time" label, thanks for apreciate my idea.
Now, with the availability of a giant datababase of asteroids I thing necesary a modifycation in the men? "Render-view options-show", in the sense of allow "show/hide" the asteroids. The reason is that, if you do not work with asteroids, but wish keep them "available" for use in the program, Celestia will be slowed for the "permanent" calculation of a lot of orbits.
Also, may be desirable a "custom" menu in order to personalize colors for planets & satellites orbits, labels of asteroids & planets etc. But, for me, your "course" is the correct course, first a good "real word estructure" and second the "gadgetts", thank you again for your work.
