So perhaps we have a different understanding of the use of a form. The form needs to transport information which can then be processed further. Any hinderance here will be an additional obstacle. So when I use forms to e.g. invite for a vernissage, I need the name, the e-mail address and any remarks INSIDE the e-mail so I can copy and paste them all together into a sheet.
Now I would have to copy the Name from the Header, the e-mail address from the header and rest from the text field. This is inconvenient. And I think it is more important for our paying clients to have a decent workflow than to stick to a comparism with an e-mail app. For this, I could use the basic form of Foundry. But the Forms should actually be more flexible this way in my opinion.
