Acts_as_wizard plugin: suggestions needed :-)

Hi guys, a few weeks ago I set up my first rails plugin: acts_as_wizard
This plugin will let you build wizards on top of existing controllers,
giving you the ability to chain pages and actions to provide wizard-like
behavior through web pages.
I bet there are better ways to achieve this goal than ones I
discovered…
What I’m kindly asking is someone who wants to give me suggestions or
hints.

Thanks a lot,
