I would like to create a button using dat.gui library. In a perfect world, this would work like this:
gui.add(\"button\", \"click me\");
This creates a button with text left aligned.
var obj = { add:function(){ console.log("clicked") }};
gui.add(obj,'add');
FWIW, dat.gui assumes the GUI type based on the target's initial value type.
