Ok - so mine finally came - and I’ve made a device handler.
some key features:
it will register button clicks (up to 5) as button pushes for ST made apps
It uses ST’s numberOfButtons attribute so you should find even for some ST made apps you should be able to use all five clicks
I’ve made a special integration with CoRE, so that you can specify the exact number of clicks or use hold start, hold release and even hold length as triggers
