I’m not much into desktop custimization and docks and things like that, but this particular dock from Nexus got me hooked. It’s customizable, easy to install and most importantly, it does not slow down your system.
You can place the dock at the top of the screen, in the middle, at the bottom or just let it stand vertically. There’s also a number of appearance effects that you can apply or visuals that you can use, meaning that you can tinker a little and set things more to your liking. Their website also mentions that it’s Windows 7 ready so that’s also good to know if you are going that route.
You can download the software here (13.3MB) and if you want to get a better look at it, just click the image above the post to see a bigger version.
