See date user was added in user view

It would be great to have a column with the date a user was added next to the date that shows last activity. 

This would make it easier to find users who where recently added, add them to lists, and get an overview of their progress.

I often create workspaces that are used over a longer period of time, not all users join at the same date. This would allow me to filter the list by date they where added, and not only activity.
