[keycloak-dev] Idle timeout notificaion

It's common for applications to notify the user if their login session has timed out due to inactivity. Then the app typically presents a popup notification and possibly an option to refresh the session. There is a customer who wants to do this for several applications in the same realm. Is this something that Keycloak could/should provide or at least help with? I'm thinking that maybe a bit of javascript could register with the Keycloak server for a notification. Stan
