What a splendidly simple, yet effective and diverse extension, with what may appear to be unlimited possibilities. Thank you

Could you add a (single/normal) click event as well ?

I also note it does not work with an imageSprite component in a canvas.

Thanks for your feedback! The single click event has been added in the latest update, and I hope it works well for you.

As for the issue with ImageSprite in a Canvas, you're right ,the current doesn't support it because gesture detection doesn't work directly with ImageSprite components.
