Contact Form Module would be improved with:
  1. an AUTORESPONDER feature, to send a DIFFERENT precompiled email message to client, when successfully compiles form. At least this feature available for WORDPRESS/SMTP sending (as sending within external apps is totally managed from external apps). Or, better, ability to choose different sending ways: for example send to client through API and autoresponder through Wordpress / different API;
  2. the ability to add rich text to checkboxes and to other fields, so will be possible for example to put a checkbox "accept Privacy Policy" linked to site's privacy policy page
  3. the ability to setup personalized messages about errors/missing input - for example: "This field is mandatory" in red
  4. add Cloudflare Turnstile to antispam services, not only Google Recaptcha
