If I understand what this part of the forum is about, one thing that would be REALLY helpful is being able to type the name of a craft into a seachbar, and KSP showing you the craft with that name. That would be very helpful, since I make a lot of stuff (Specifically cranes), and I can (almost) always remember the name of the crane, but it takes me a while to find it. Being able to just search for a specific thing, instead of having to scroll and search for it, would make playing KSP a lot easier.
Well, maybe not a LOT, but it would be nice anyway.
