This one comes by way of an email from my Dad. He brought to my attention a FREE piece of software that really allows you to take control of gestures on your Mac.
Meet BetterTouchTool. I've been trying it out and I have to say, it's quite handy. I have a laptop with a built in trackpad. With a triangle gesture I can now open my Mail app. With what they call a TipTap Left I can launch my calendar. BetterTouchTool is packed full of features that let you configure actions for keyboard shortcuts, gestures, and even has a built in window snapper allowing you to quickly resize and position your windows. Even users with a magic mouse can benefit from BetterTouchTool. Lastly, I didn't try it out, but there is an app for iOS devices that allow you to use your iPad or iPhone as a touch surface remote for your computer.
Leave me some comments! Let me know what you think!
