Devices count in users view

[GiedriusVdk]

Is there a way to make the user view more customizable in admin? Or at least add the amount of user devices. Because now it is difficult to determine this, it is necessary to check each user. Now it's a problem because there are empty users who just sign up and don't add any devices.

Describe the solution you'd like
It's enough add one column in users view with devices count for this user.

Thanks.

The problem is that the query to count number of devices per user is expensive. Because you can have groups in between etc.

I understand, but since this is rarely needed, maybe an option can be added e.g. "Show additional information" and then perform a query and refresh the view. This way, the default view will remain the same.

Another option would be to export in that view window, where you can add more necessary values. I suggested this because when there are many users in the system it becomes more complicated to administer them, I think you understand.
