Hi Miles,

Have you seen FOOTPRINT_VIEWER_FRAME::ReCreateFootprintList()
(pcbnew/footprint_viewer_frame.cpp)? It might be the easiest way to go.
Perhaps it could be wrapped in a function provided by the scripting
interface.

I could not find 'includefallback' option you have mentioned, would you
point me to the relevant source code?

Regards,
Orson
