Currently, bitmaps are rendered in the order they are given. Thus, if I have a planet first and a nebula second, the nebula will be rendered on top of the planet, which looks daft. This is extremely frustrating, especially if I've decided to add a few more nebulae in a certain area after I've already added the planets.
What I'm requesting is the ability to move each bitmap entry up or down slots. Thus, with the planet, I could just move it down a few places so that it comes after the nebulae, thus being rendered on top of them.
Don't hurt me.
EDIT
And another very quick request: Can we have an "indicator" that easily allows us to check whether or not we have 'Control Object' mode on (the thing you get when you press "T", it allows you to use the movement keys to move the currently selected object(s)), it's sometimes kind of annoying when you've just got everything set up correctly, then you want to zoom out and mess everything up by moving some ship 1000 meters backward. Possible indicators for movement and rotation speeds would also be helpful...
