Is it possible to have the element "text" (which the customer enters) in the order details? The element (and also the element properties) are visible in the email, but I really would like to have this information also in my order details.

This is really not possible?

Yes, and that is indeed visible and saved - don't really know why they don't also save text input as well. The text is visible in the cart - but not in the order details.

So text is absolute not possible to show in order details (so added to Color, Font and size)
