How about “Try on” button that will show you customization screen where you could try how the ship will look like with different thrusters/paintjobs/models/paint? For example, you found M404 and M408, but you don’t know how they exactly look like and what the difference. You click “Try on” button and select any type of ship, color, thruster etc. After this you know what you need to buy to be .
Something like “preview”? I like the idea, tbh.
