This is the best mouse gesture extension I have used, and I think I have tried them all – this extension is better than anything available on Chrome, too. The settings interface is very clean and intuitive – assigning gestures and choosing preferences is easy to understand and all work flawlessly (in my experience).
It has a plethora of built-in commands to which you can assign whatever gesture you want, and every conceivable way to launch them – gesture, scroll wheel, chord (aka mouse button rocker), combinations of previous, and finally, user scripts for commands not already built-in. This add-on might be the only one that allows gestures in 4 and 8 directions (the 4 extra along diagonals). When using 8 directions, the user can choose 8 equally spaced zones, or, use wider zones along the diagonals. If you use 8 direction mouse gestures in other programs, then you will likely understand why that matters.
And speaking of user scripts, the add-on author was exceptionally helpful. I sent him an email to request gestures for: Mute Tab, Mute all other tabs, Unmute all tabs. He responded in 1 day and posted the necessary user scripts on github. He explained in his reply he did this so I could download the scripts and have my desired functionality immediately, instead of having to wait for him to update the add-on and then go thru the release process, which could take a couple months - now that is above and beyond… my thanks to you again for that Mark - you are outstanding. FYI… all three of my “mute” requests are now part of the built-in command list. I have tried at least a dozen “mute tab” extensions, and none of them remotely compare with how efficient these new Foxy Gestures mute options are to use. I run 4 youtubeTV channels with 1 channel in each corner – no more trying to click a tiny speaker icon to mute one channel and then unmute another. And when you are in full screen mode, the mute option for other extensions is not even directly accessible… another reason this one is so much better.
The only thing I could possibly wish for is that the author would create this extension for Chrome as well.
