So, I've been thinking of coding my own external blueprint editor. I think I have a pretty good concept for the program's design. It's basically a multi-layer paint program with every pixel representing a block. There's also a 3D view so you can preview your ship before it's built, a speed/weapon strength/power/shield calculator, and a ship-segment copy/paste and any-angle rotator. There's a lot of other concepts I have that are still in the planning phase, these are just the things I'm sure...
