Ligend,
We're very, very happy that you're pleased with our extensions. We do have plans to create Twitter (and Google+) social integration extensions later this year, but have not started yet. We're currently in the process of reducing and reusing code in both our LinkedIn and Facebook extensions so that we can leverage that experience to make more social extensions.. however, it's not expected that we'll even start either Twitter or Google for a few months. Once started, it will take a few months to nail down features and get something out.
If you're in a rush, unfortunately, I'd have to say we won't be able to help you.
Thanks again for your feedback, and best of luck,
Alex
