Personally I'd love to see some inspiration taken from Wufoo and Google Docs.
I've been looking at the roadmap but it doesn't give me a good picture of the ajax plans. Will the development build on KSS or will the Ajax functionality be done using more JQuery? Or will it be a mix of both?
I think it is a super useful product but it isn't as fluid as it can be. Recently I've found my self using Google Docs Forms for quick forms, however I don't get the level of integration that I can get with pfg.
