This idea has been merged into another idea. To comment or vote on this idea, please visit APP-I-892 Display user activity (Last login & time spent in Aha!) to admin users.
It would be useful to see when the user had any activity using aha. A good place for this information is the Settings/Billing/Users as a column, so I can sort by it and see who is not really using aha, so some paid seat maybe can be reallocated. Last activity can be time of the last login for simplicity.
This would be very helpful when trying to reduce the cost of contributor licences.
