Thanks for answering my quesitons. I bolded because I'm not sure you'd see this in all the clutter.
I read somewhere that the 'tracking' or whatever isn't something that can be manipulated in the current version of the editor (obviously not, since you can't click it). Will this feature ever be included?
Also, another question: why can't the space map textures be changed? The 'texture' menu isn't accessible when you make a space map, so I can't put the image of space in the background. Is this a bug or is there another way to import a texture?
