It would be lovely to see unbounce add some PhP integration to this awesome platform. I know that unbounce is mostly targeting the non developers, but as a developer myself it would be very handy if we could have some PhP functionality.
It would be nice to see even the most basic features, for instance firing onload functions to dynamically request data. I think it would make a page more dynamic and it would then also cater to a different target market, us developers.
I just wanted to make a quick recommendation, let me know what your opinions are.
