I've created a GitHub repository for my KiCad footprints
https://github.com/aewallin/awallinKiCadFootprints.pretty
Maybe some day schematic symbols will also follow this foolproof convention of
- directory <-> library
- file <-> part
ToDo: polish up some of the footprints, check if they adhere to the Kicad Library Convention, and try to get them included in the official libraries.
