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.

Yeah, RD is awesome.  Since I can't put a toolbar up at the top of my screen since using win7, it has been a life saver....kind of.

The task bar yes, but not a toolbar.  You used to be able to drag the My Computer icon (or any folder) to the top of the screen and it would make a toolbar with all your drives (or files in the folder) at the top of the screen.  Win7 does not do that anymore.  Even Vista did it.

^^ I like it.
