Got a couple bugs to report:
This is a strange one and quite severe. It's exactly as it sounds: the form can no longer be changed.
I'm in the Form Fields tab adding form elements to an existing form. I click "Save Fields" and the page refreshes but my form elements do not appear. When I bring up the form I notice that my changes were not completely saved. It seems to save new form elements I added but does not save either their position nor how I've edited them.
I wonder if it's because the form is particularly long. If you give me your email address I can send you my WP database and you can take a look at it.
Custom CSS Classes
Class names are appended with an identifier based on their form element (e.g. '-wrap' for radio buttons, '-field' for text fields). I hope this isn't intentional because it makes it impossible to use specific class names when importing CSS libraries like Normalize.
