and I would love to see a regular text area field for "in-between" texts
Argos, it is already there and it is called html field.
But it is only for people who are able to use their mind

You know, some people love tables and others love div forms.
So if you want to put something between the fields, you have, of course,
- at first close your table or div or whatever you have
- write the extra content
- at last reopen your table or div or whatever you have
The module won't do it for you, to give you the maximum level of freedom in your design.
Yes, I know how the html field works, I aleady found out that myself. But it's not user friendly for two reasons:
1. you have to add markup code, which I cannot expect my clients to do when they create forms
2. when you do use markup, it works fine in the form, but it messes up the output, because then the markup has not the context of the form anymore, but of the website and/or email.
Try it and see for yourself...
