Add a texturing tool or an interior surface. That armor texture everywhere is unbearable.
I think one of the weakest points of building in Space Engineers is the fact that no matter what you build, you're generally stuck with that single armor texture almost everywhere.
It's arguably very ugly as an interior surface, prevents good immersion, and makes it more difficult to enjoy the result of the many hours of work we put into building things.

I'd argue that an alternative texture (I think smooth, no scratches, no lines) needs to be the very first decorative addition to the game.
