A short list of small things that would make it even better.

-Ability to round wing tips / control surface.

-Greater flexibility with sizing and rounding of structures.
(Instead of everything being 1, 1.5, 2, etc.. make it in denominations of .05)

-Greater customization of landing gear so you can change the height, length and width.

-Have an X, Y, X axis handle on parts in creation area with ability to scale and change independently on all axis (X,Y,Z).

-Make cockpit sections customizable in size (X,Y,Z).

Thank you for an amazing game and looking forward to seeing this game grow in capability and customization (.. and possibly realism?).
