Simply put, it has a nice balance of interaction for the user: For point and click lovers, the hover over the useless third plus/zoom button on Macs window bar becomes a minimalistic powerful tool. For keyboard dependents(like me), the default settings work well and if you want to get specific, you can customize to your hearts content. Takes multiple displays into account. The grid and cheat sheets are nice new features. Lion approved. Gave 5 stars for now. Would love to see multi touch incorporation in future updates to complete the point/click, keyboard, and multitouch trifecta. Thank you.
