Documentation

This looks like exactly what I need and I plan to but the pro version, but I cannot see any useable documentation of how to create a form

The sum total I have found so far is

Drag form elements from the left column to the center.
You can delete form elements by cliking on the trash icon editing the field or simply drop in into the trash can at the bottom.

3. Click on the title, input or helptext to trigger the corrosponding settings (Input settings differ from field to field). Note that you can duplicate the field or add it to your clipboard to be used in other forms.
4. You can preview the form by clicking on the preview icon (notice that you can change the device)

and

Please make use of the interactive tutorial found by clicking on NEX-Forms top right! Use your keyboard arrows to navigate the tutorial

This second one I have NO IDEA what it means as I can see nothing on the top right to click.

I’m more than happy to pay for the product which looks like just what I need, but help me get to the interactive tutorials !!!
