That's not a functionality lack,
But periodically reloading pages look not very user-friendly in the age of web-2.0
Browser moves page to top, while user may be looking at the bottom.
When an alarm is sounded, browser may popup annoying alarm window, if there's no builting wav player.
And obvious drawback is absence of real-time notifications for real-time pages like agent live, online monitor, wallboard, and for "realtime live".
Turning all these in real live will significantly improve QM usability.
P.S.
There exist several
comet-solutions, for such style of notifications.
