T39: a session's row shows its status, the most pressing first: waiting by its kind, an error, work with Ely's progress ring or a still loader, done, then a failed last command, then idle; hover lists each record's state, app, title and message, disarmed and cut; typing sees done and error, herdr's aside; a hidden session that starts waiting sets its title strong until shown
