I would like the option to create more detailed motor shapes. Specifically it would be cool to be able to design a motor that is non-cylindrical, like one with a taper or spherical casing. Maybe even make it like the freeform fin design system. Also would need to be able to import a user created thrust curve to the newly created casing. I know that ThrustCurve tracer requires you to define motor specs, so would need to override those.
