Hey Kevin. Regrettably, this sort of file sharing doesn't quite work in the tool today. There's no way I'm aware of to have a single dictionary file that gets "accessed" from different projects - no sort of central file that can be updated by multiple projects, that is. You can certainly start with a single dictionary that you then import into each of your individual projects, but it's not a "live" update that will subsequently edit the original dictionary file.

And if there's anything else we can help with, let us know - here, or by emailingsupport@serlio.com .
