Dock-It: multiple Dock manager
In this week's Ask TUAW we addressed a question about adding a Dock to each screen of a multi-screen set up. In researching that question, I came across a nifty little app for doing just that called Dock-It. As you can see from my rather extreme screenshot above, it lets you set up multiple Docks and pin them to any of the four sides of the screen, including the top. And of course, you can create docks on the secondary display as well. You can also add little "Applets" to your Docks including a clock, system preferences, and a very convenient shelf (e.g. for holding files when you're moving things around with the Finder). Finally, you can browse your file system simply by clicking on one of Volumes or Folders which you've added to one of the docks.
Dock-It looks to be a very versatile piece of software and well worth its modest $10 price if you're into the idea of more Docks. The only downside I've seen in my testing is that it can quickly use quite a bit of real memory, especially if you start browsing through the file system. A 14 day demo is available for download
