Action Launcher is something special. The home screen replacement made its debut a short three months ago in December, and found its way into our hearts as one of (if not the) best app of the month. What makes Action Launcher a great replacement is that it's unique – AL is totally different from any Launcher we've yet seen, and it earns that distinction with a couple of signature features: first, all your apps are a quick slide away.
Last summer, we saw the launch of Tweet Lanes – a beautiful, functional Twitter app that – due to Twitter's reformed API – ceased active development just a few months ago. Today, Chris Lacy has issued a "further update" on the status of development, writing in a post to Google+ "just because I am no longer actively developing Tweet Lanes doesn't mean that development of the app has to stop."
Yes, after "countless requests" to do so (and an offer to sell), Lacy has taken the project open source – opening up the TL client itself, its SocialNetLib library, and its associated AppEngine project.
