I'll scan your computer for your sym-lib-table / fp-lib-table and your personal symbol, footprint and 3D-model libraries, then load them here. Nothing is changed on disk until you press Sync.
Fetch an MPN's symbol, footprint & 3D model from the Adom wiki and file them into your libraries. Written to disk on Sync.
Create an empty symbol or footprint in a library, then fill in the fields inline.
