Older version should not have been abandoned.

This app has been quite useful, but I was very disappointed when the version I previously used with Snow Leopard 10.6 on a separate partition completley stopped working, suddenly complicating the task of keeping that Apple address book sync’d too. Too bad, because it was a perfect solution for all my stuff for a while. Now its only a partial solution. Would be greatly improved if also made directly compatible with Fruux, Microsoft and iCloud address books.
