Going to try suggesting this again as I think it would be a killer feature and perhaps I did not describe it best the first time. The ability to add envelope distortions to a text string so that a customer could enter their custom text and it would then conform to a variety of "envelopes" that we define in the layout. (See Adobe Illustrator)

It would be great to have a wrap image/text option in the editor, it is especially hard to show the customisation when the product is a circular/cylindrical object like a bottle or mug.

Please see attachment for what kind of option i meant.
