I have 2 feature requests, one which you (the design team) are already aware of...

The first is to make the captcha for the contact messaging an optional setting for when the page is only available to logged in users since they are already verified members of the site.

Second is to be able to enter one contact and be able to assign them to multiple categories. When using the component for a variety of purposes, it is quite possible that a single person may be assigned to multiple departments, teams, groups, or however the categories are setup. Allowing one contact to be assigned to multiple categories would eliminate having to create duplicate contacts which is currently the only way to set that situation up now.
