To access the preferences panel, and more, just click the newly added icon in your menu bar, here:
The preferences panel will look like this:
The default settings are recommended by the developers, at least to start out with, and I’ve found no reason to change them. They provide you with simple pop up boxes that will pop up as soon as you mouse over a dock icon. Once you do that, you can move on to the next app in your dock, or simply click a window to maximize it, or bring it to the front if it was already up. This is super handy for applications like photoshop or web browsers, where you tend to get a bunch of different windows open pretty easily. The pop up are elegant and non-intrusive. By default they appear like the example below, but can be tweaked pretty extensively as far as size and appearance.
DockView is free to try with rare pop-ups asking you to register, but a license is a great deal at $7.99. While you’re over at Kapeli’s site, they’ve got a few other inexpensive apps for Snow Leopard that are worth checking out as well. Is this a feature that you like in Windows 7, and are glad to have on your Mac? Should it be included anyway? Know of any other cool programs to bring extra features to OS X? Tell us in the comments!
