Hi dev team, Fist of all thanks for the great work you've done already. It's a pretty awesome game, and it helps me forget about my frustration of aerospace not being funded enough. Here's my suggestion: At the moment we have access to 2 solid boosters, which kind of limits the possibilities since you have to multiply the boosters to achieve your goal. I would love the idea of doing our own booster. To make it not to hard to design, this could include parameters such as: Length of booster Diameter Grain geometry (star-shaped, cigarette burning type, or a simple circle for example... => gives you basic thrust profiles) Thanks and keep up the good work!
