More Fuselage Block Shaping/Forming Options
Suggestion 1: Fuselage "Twist" Property:
In the fuselage editing box there would be a new slider below the fuselage block size and corner selectors, that when moved would twist one end of the fuselage. You can twist left/right sides or front/back. Range from -360 to 360 degrees. Maybe a little button above the slider as well to choose which side to twist. This would make complex shapes an absolute breeze in the game, such as wings and stuff.
Suggestion #2, Left/Right Scaling:
Allows you to change the size of the left and right sides along with the front and back. Again, more possibilities with complex shapes.
You can do this with fuselage inlets
