Thank you patio11. That's a great tip (starting non-empty) - more so given that it's backed by actual data from your site.

[I have edited the following paragraph a few times revising my understanding of the definition of live-preview as I go along] With regards to the live preview: by live-preview do you mean editing the text in rich-text editor fashion within the actual page? Or, just applying attributes as they are changed in the attribute editor without the user having to click the "Apply" button? The former would be hard I guess. The latter should be easy.

Regarding element placement, it can be confusing right now. You might be scrolled down all the way, add a text field and not even notice because it's placed in the top-left corner. Drag and drop would be the way to go.

Thanks, these are subtle yet crucual points you're making - your experience is invaluable.
