Related to point 2 - should Webhook refuse to allow instruction fields which have the same label?
Are instructions meant to be available to the front end? They aren't listed in the docs (http://www.webhook.com/docs/widget-template-reference/) but the scaffold will generate output for them (only a label, no value obviously)
The error styling on the fields with errors is correct. Did the instruction text change to be the error? I was not able to reproduce that when I tried.
This has been fixed.
It doesn't hurt to have instructions available in the templates.
