Multi-touch usage

Up until April 2019 UPDD Gestures could not be used to control touch-enabled web pages.

The problem is that OS X doesn't pass its system-level touch events to web browsers as HTML5 / javascript touches. So while these pages will work with an iPad (and similar) they do not work in OS X, even when using Appleā€™s magic trackpad.

However we have now created browser extensions for Firefox and Chrome that does cater for multi-touch input as described here.
