This is an enhancement request.

Wizard buttons can be modified via the activate event and replaced with a fully initialized Button, but it would be better to just offer more of the Button properties right on the wizard steps.buttons object properties.  For example, the icon/image properties, fillMode, size, etc.

If the Wizard has too many steps, they start overlapping. Consider implementing a way of indicating there are more steps, without displaying the steps. For example, the Pager adds an ellipsis in the middle, instead of displaying dozens of page numbers.
