Omada Controller has this Clients list where you can see all connected clients. You can click on a client and go to the Config tab where you can configure a few things like a name and some checkboxes.

But as soon as a client is disconnected you have no way to find these settings for it again. It's being stored in the database, but you cannot do anything unless you connect the client. It makes it really difficult to cleanup old clients. You should be able to find everything that is permanently stored and have an option to forget it.

If a client has stored configs, it should show on this list, even if it's not active.

The strange part is that you even include a big green "CONNECTED" status for each client. But there is no "DISCONNECTED" feature seen as the clients just disappear when not active. So why the status indicator?
