Something that sucks is that on the Player Info screen online you can only see the right side of the ship.
as I see it there are three ways to see the custom skins:
1. online/ingame, which is the worse quality.
2. in the player info screen, which is the 2nd best
3. in a community like this or send a file to your friends - best quality.

I'm guessing most of the people use 1 and 2.

A selfrotating ship like in the save screen in the skineditor
or being able to rotate it your self with the nub would have been nice.
