I love Gravity Forms, I use it on a majority of my own sites and customer sites. It suits 99% of things I do.

The overhauled UI is going in the right direction but I still think things are way too big on the actual form editor page. Dealing with big long forms is still a long and annoying chore.

Slim things down more like how the notification page is and it would be perfect.

The Add Fields section is perfect thought.
