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?
