Add possibility to duplicate forms
When duplicating a form I have found that the slug of the old post gets copied (with a -2 appended to it). I think the more natural behaviour should be that the slug should be regenerated from the title. This is a simple fix in the Admin.php model, on line 789, just replace '$oldPost->post_name' with 'sanitize_title($title)'.
Correction: This is not as simple as stated above, as this is executed before a new title is given.
