You can preview the plug-in setup as you would see it in page designer. You can either do this by clicking this button in the top right corner of each example, or you can see all the examples together in the region below.
Looking at the examples you'll see just how easy the plug-in is to use. Don't worry about changing any values as they aren't saved. We actually encourage you to change them, so you can see the behaviour of the attributes and their help text.
