By far, the best of the best Gesture Add-ons I've ever used. Tons of options. Highly customizable. My only complaint is not available on every browser.

I was kind of surprised it's been rated lower than 5 stars. I read through a handful of comments, and have to admit some of the 4 have suggestions I'd like to see too. Some of the two and three stars, offered some sage advice to follow backups with a screenshot.

As far as the 1 star ratings, apparently some users have had identification problems. I haven't noticed a problem with that. If it helps anyone, my deviation is set to 0.15. I have no idea if that was the default setting, or something I changed along the way, but If you're a little lazy about execution, like I am, I'd recommend giving it a try.

Extra sloppy executions still get misidentified, occasionally. To compensate, I separate polar opposite actions from semi-similar movements. My gestures with varying properties to open a link are kind of similar, but all of them are entirely different than my gestures that effect the a tab, or windows state.
