a few usability enhancement ideas:

* javascript to auto-generate the slug based on the form title would be nice.  Similar to how EE does things, when the slug field is empty, as a user types in the page title, the slug is generated, converting spaces to underscores or hyphens (could be config, or default to underscore).  Once the slug input has a value, changing the title doesn't change the slug.

  * display a warning if a user tries to change the slug after a form has already been saved ("Warning: changing the slug will cause the link for this form to change.")
