I'd like to improve this during the V6 > development cycle. Radical proposal: - symbols and footprints are stored in content-addressable repositories similar to git's objects directory - schematics and boards reference library items by their checksum - any part that is used is copied to the project - modifying a part creates a new object that contains a note that it supersedes the old one - parts are saved into the user home directory or (if configured) an organization wide shared folder - the entire library path is scanned for parts, and the results merged to a common view This would solve a number of problems: - projects always have copies of the parts that were used, without needing to copy them into the design files - we can detect when projects use parts that have been modified since, and allow the user to upgrade if they like (but they can defer indefinitely without risk) - path configuration is reduced to "where the system library is" (handled by distro) and "where the company library is" (optional) - libraries can always be written to The actual directory layout of the library directories does not really matter, so we could also allow zip files, add directory indexes or do some neat stuff with indexed extended file attributes (which ext4, NTFS and HFS all offer) through plugins without the main program having to care about that. The "supersedes" mechanism will need some more thought, as we probably don't want to keep all intermediate versions, but we need to know their checksums in case we encounter them -- maybe a file that lists relationships between parts that have been removed could be sufficient.
