Just uploaded KiCad files for a board I designed for fabrication at JLCPCB. I have `LCSC` part number properties on everything. CircuitHub didn't recognize any of them. Would be nice if they had mappings of footprint-equivalent parts from JLCPCB's "basic" library, so I didn't have to spend hours re-sourcing (and possibly re-footprinting) everything.

Love that it's fully self-serve and not "please call sales", and will give this another shot with new board designs when I still have total flexibility in part selection. But for existing projects I'm probably just going to re-order from Shenzhen.
