I like idea. Actually i was using this type of form system on joomla with custom code. Really didnt try on gravity forms yet but what do you think about this? possible? supported?
I just saw this today also, it's interesting. It isn't really possible with Gravity Forms right now. Maybe in the future something like this will be possible, we do have ideas for more free form style form editing... so hopefully down the road we can make it happen.
