This is a great start, well done! Eventually it would be amazing to import (for example) a buck converter circuit with a wide voltage input, fixed output suitable for RF, and have it automatically check available components at JLCPCB and then lay it all out with, adhering to best practices (ground planes & capacitors right next to pins etc.) If the available components change, it can tweak the footprints and layout without having to start from scratch. Good luck, I’ll be following closely!
