In Release Task Drawer, for all 5 email fields (to, cc, bcc, from, reply to) in Notification task, we are planning to add user selector.
It would show user Full name (or Release username if Full name is not available) and email. This would allow searching by email, username, and Full name. When clicked on the search results, it would fill in with the email address.
Interesting to hear the feedback if it's something that you are looking for.
