Here is a list of things we want to do or just some ideas, but haven't been done yet... (in random order)
Paging / Steps
Create a form divided in steps (pages)
Create a predefinded form (contact, signup, etc...)
Charts & Reports
Building somesort of charts or reports. I have no vision about this, but I think it could be usefull. So the addon can also be used as a survey tool.
Redirect based on entry
Redirect to a page based on the submitted values.
