Yeah, you're a bit behind the curve on this one, but it's a solid app. I use a similar app on my laptop at work called
RKLauncher and it's very handy to have, especially when I'm multi-tasking like a mofo because I can have all the convenience of a large "Quick Launch" toolbar but without taking up a lot of space in the taskbar. It auto-hides and stays out of the way until I mouse over the top-center to bring it into view. It looks like RocketDock is very similar in that regard, but it looks like it has good community support with the add-ons and skins and such, whereas RKLauncher seems to have stagnated and I don't think there's been an update to it in a couple of years.
