Given that we have significantly extended our API, we should probably add this new type tp our user guides! It may duplicate our actions, but maybe we can find a good way to do so

Hmm.. I see your point but we would essentially duplicate our user guide on the Button (that is currently living under components) under controls as well. We could add in a section under controls and then link to the content in components? Just pushed that change - let me know what you think

Glad to see that ControlType supports vm.Button.
I left one comment, but other than that, the PR looks good!

Closing due to decision to not add Button as an officially supported ControlType and instead go via the route of custom components such that the user can add the Button as a ControlType themselves via vm.Page.add_type("controls", vm.Button)
