Gnome Do 0.8 has just been released! If you don't know anything about Do, I HIGHLY recommend that you check it out. It is a magical launcher inspired by Quicksilver that is super powerful, plugin-rich, intuitive, and rather polished.
The 0.8 release added a bunch of bling in the form of smooth animations and more attractive interfaces. One of the most interesting aspects about the release, however, is the addition of a Dock interface called Docky:
At first glance it appears to be just yet another Linux dock and a random feature for Do to add. However the dock is actually automatically and dynamically populated based on your most launched applications in Do. You can also add and remove launchers by dragging them to and from the dock. This would be cool enough, but it doesn't stop there because Docky is a first-class Do interface where you can perform all your actions!
Oh yeah, and it features a silky smooth parabolic zoom. Instead of repeating what the developers have already said better themselves, let me link you to their blog posts. If you want to get Do, check out the first link which is the official release announcement (or skip right to the PPA :). For more in-depth information, I highly recommend jassmith's post who was the main Docky developer. Happing Do-ing, and don't forget to Digg it!
