In my blue-sky on the subject, I mentioned a database of selection criteria, and the criteria could be part-specific or project-wide. So if you had a field for "hand-solderable" that selected between normal footprints for reflow, or extended pads for home soldering, you could use that field to select alternate footprints. But that assumes you have a fairly complex database mapping groups of symbols to groups of components which select groups of footprints. *That* I've used before, way back when, but it was a very small database. > OR..

We started with the m4 library and migrated to a fixed library to better support Windows and the parts library dialog, but if we can come up with a better way of doing it...
