For the coach “Home” page notification “feed”, please allow users to toggle “read” and “unread” for specific notifications (or “flag” some other way. Use case: I read a notification, but want to return to it (maybe requires more thoughtful reply or analysis) so would like to re mark it as “un read” so I don’t forget about it.

For the coach “Home” page notification “feed”, the “read”/“unread” filter should out rank the others and you should be able to filter on “read”/“unread” in addition to the other filters simultaneously. So as an example, I would like to be able to view unread notifications with comments. Or only unread metrics. Ideally the “Mark all as read” toggle would apply to whatever you are filtered on.
