This is the feature request area - so one feature that I'd love to see is if GF could be designed to be more novice user friendly Easy drag and drop (at least two columns) or pre built templates would go a long way to helping newbies and those who are CSS impaired.
A premium Form Design plugin would likely encourage many people to upgrade....
I also wanted to let you know how much I appreciate the ease of the back end - setting up forms using conditional logic has never been easier - and I LOVE being able to pass the info from GF to Freshbooks (that's why I bought your plugin btw).
If someone wanted to design an event registration plugin that integrated into GF I would be thrilled - something like event expresso but which retained the flexibility of GF and the integration into your payment gateways.
This is a great plugin and I'm looking forward to seeing where you go with it in the future.
