The classic interface is still present in BreezingForms with nice improvements such as element highlighting and draggable form area.
Easymode was a pleasant surprise. I've used this new interface to build up a multiple page form and I'm really satisfied with the result. The tabbed interface and draggable form elements really make it easy and fast to create forms. Not having to navigate to another page just to set form/element options is a huge time saver.
Form preview is great also.
Overall, nice bevy of features for a competitive price. The video tutorials, documentation and support are superb. I highly recommend this extension.
