This is a really nice piece of software for anyone with a dual (or more) monitor setup.
The really nice “killer” app is the ability to extend the task bar across all you monitors. This is really useful and improves your productivity, and its really cool too!
It also has some nice other features too. Unfortunately it is Shareware so you’ll have to eventually buy it, but you can get a free 30 day demo before you take the leap, here:

Just remember this: your going to really miss it once the 30 days is up!
