Firstly, this looks like it's going to be a great product so keep up the good work.
So caveat - I'm not a web developer, just a simple programmer, so I have a simple question.
Why when I hit Preview is the view often very different to the Designer mode. Even though preview is super quick, this does seem to defeat the idea of the WYSIWYG editing doesn't it - or have I just made up the "WYSIWYG" bit?? I just have a label under an image, and the label positioning can vary quite greatly from Designer when I hit Preview. ???
