Downloaded the latest. It's a great tool and makes form building a breeze. A few things I noticed.
1. Classic version allowed for a form field to be [inserted] into the subject field of the recipient's (form owner's) e-mail. I have customers that demand that feature and I can't use your tool unless it's available or I can at least modify the code to accommodate it.
2. When sizing the fields to 50% or less, they appear inline instead of stacked. There doesn't seem to be a way to prevent this. That would be nice to have. I'm sure there's a work around but thought I'd mention it.
3. In the form properties there are two fields labeled "width" which is confusing. That's just a clarification issue.
I like that you've moved away from flash and have embraced HTML5. Kudos for that. It provides clean, browser compatible code, or at least I suspect it does. Looking forward to seeing the actual code it produces in the CSS, Javascript and HTML files.
You guys are progressive rather than resting on past laurels. I like that. Keep up the good work! --Todd
