Thanks to @rbytes for prodding me to include touch events and to @GoToLoop for introducing me to the joy of CDN (Content Delivery Network) both of these features have been included in v1.0.0
In particular the CDN means you don’t have to download any files to use canvasGUI in your own sketches, a simple addition to your html file is all you need. THis change is documented on github and on my website.
The CDN link also works in the p5js web sketch editor as shown here.
