Hi,
I have (probably) finished the plugin, i.e. at least as far as new
functionality goes.
The plugin is now able to synchronize any changes to BibTex keys,
including complete change of format, LyX document is updated
accordingly. This is useful when the reference is incorrectly collected
in Zotero and inserted as such into LyX. Probably not something that
would happen that often, but since it was quite straightforward to
implement...
