The admin conversations dashboard lets admins keep up with ongoing conversations happening between businesses and developers.
It's not very obvious what two columns, REPLIED? and EMAIL?, mean.
A PR addressing this issue should:
•  Add a title HTML attribute to the two headers explaining what they do.

The HTML title attribute appears as a tooltip when hovering the element. Use the following titles:
• REPLIED? - The developer has replied to this conversation.
• EMAIL? - The developer mentioned an email address in a reply.

This will most likely require changing the Admin::Tables::HeaderComponent View Component to accept a new attribute to be rendered.
