I will start by saying I have loved this extension ever since the first version. The only reason I'm giving it 1 star is to attract developer attention to a very annoying issue with the latest version 3.0.1.

Let me paint the picture first: Users who install gesture addons, like me, and you - who are reading this now, are very particular users. They value convenience and ease of use. They want effectiveness and elegance. In the case of gestures - they have to, first of all, work. And work well. When I draw that L-shape on the screen, I want to be sure that in at least 95% of the time it will get recognized and trigger the action I need. Otherwise the addon becomes more of an obstacle than a help. You have managed to be that reliable rock-solid addon for a long tim for me.

With the version 3.0.1. unfortunately, I have immediately noticed that something's wrong. My gestures are no longer recognised effectively. It seems now, that the length of the lines I draw have something to do with the recognition process. I can no longer draw a shape that starts and ends properly. Now I have to be sure that the length of each segment is correct. This adds a layer of complexity that I do not need, and am not willing to adopt. It is unnecessary. It is more complexity, less convenience. And for the sake of what exactly? I'm not sure.

I reverted to the version 2.1.6. which seems to work as it always has. I will use that for now.

But the most important take away for you - the developers - should be that I will now start looking for alternatives among your competitors. I want to e up to date with addon versions for the sake of security, and if your addon still does not work as expected, I will regretably switch.

Let me leave you with this simple thought:
"If it's not broken, don't fix it."

Hope I was of help. Cheers.
