I'm loving the new prototypes feature, but I think it could be even better. I'd like to be able to create research projects for parts I don't have the tech for. Currently, if you make a prototype using tech you don't have, like a twin gauss turret when you haven't researched the gun yet or an engine with fuel use 0.5 when you're only at 0.6, the part has (FP) next to it in the class design window, and the button to make a research project from it is hidden. Even when you finish the necessary techs, that button never reappears.
