In the editor of our new app you can add people to the project and assign them (editors/reviewers). When adding them to the project you can filter all users on the account by predefined user-groups (design, development etc..)
So far so good.
The only system generated list item (and that's the one we are searching for an appropriate wording) is the one shown on default (Screenshot 1) that will display a list of all users added to the account below the dropdown, whereas the other list items displays all members of a predefined user group a customer has set up (Screenshot2: list item 1&2 user generated). We decided on that because it makes it easier for users who haven't created groups or added all co-workers to different groups.
We've tried different microcopy variations: "No group", "General", "All people" and we also tried leaving it empty Not really satisfied with our results here so maybe you've got some ideas that help us out?
