It's good, works well, only real complaint is it's a little 'strict' with how precise the gestures have to be. I've used many of these over the years. I use 'up-right-up' to copy a tab, and only with gesturefy do I have to redo that gesture several times before the extension accepts it. It has to be pretty close to 'right angled' turns. Moreso than other apps I've used.

And it's also missing one function that an older extension used to have. To be fair, I'm not sure any of the current ones have it. That's the ability to distinguish 'new tab' and 'open link in new tab' with the same gesture.

I used to have 'up' as create new tab. But when I would do 'up' over a link, it would open that link in the new tab. Cool feature that no one seems to do any more.

Edit to add: I can't find a way to reply to the developer so I guess I'll just do it here and if he sees it he sees it.

I believe I did have the 'combined' matching algorithm selected as that was the default and I wouldn't have changed it since I'm not sure what it does. I'm currently trying out the suggestion to use the "open empty tab" setting but so far it's not working. Tried it with some links off a DDG search. It only opened a new (blank) tab. We'll see.
