Form Toolkit vs. Form Builder and Datepicker customization

I am a bit puzzled... are you promoting Form Toolkit as an option for customizing CSS Form Builder?

I really like the features offered for customizing Captcha and Datepicker in the Toolkit but adding Captcha and Datepicker to forms using Form Builder is a lot quicker. Once I add a Captcha and Datepicker field using Form Builder - can they then be customized using the Toolkit or do I have to add them using the Toolkit? Can custom settings for both be saved in the Form Builder presets? Please tell me how these 2 extensions can be integrated for easier use.

I would like to be able to change the color scheme of the Datepicker (with the Form Builder extension) but have no idea how to go about it. Would you please steer me in the right direction??

It would be great if you could come up with a version of Form Builder allowing for customization of the Captcha and Datepicker fields without having to use an add-on that makes the overall use more complicated.

Thanks
