Thanks for the feedback on our new CSS Form Builder tool. We used to just have a tool called the Validation Toolkit, it was an extension that would allow you to add in validations to a web form. We had many request to have a more capable validation tool that would also let you build out the forms and apply the validations in a single approach. This is what the CSS Form Builder is designed to do, allow you to create a form for just about any purpose and choose the elements that are in that form and apply validation. It can also be used on existing forms that are already in place.
While there are many other features offered by the tool this is the primary intent, create forms and apply the validations. While pointing out a competitor tool that you find useful is helpful it would be most helpful to get specific feedback on CSS Form Builder and it's functionality in regards to what you like about/don't like about it as well as any suggestions for new or different features that would be helpful. This type of feedback will help us to produce more robust and feature rich versions of our tools.
