Notification bubbles should stay on the screen forever

[Doktor M@buse]

Is there any tweak which forces the SMS bubble notification (or any other notification) to stay on the screen forever untill it has been read?

TIA

I'd like to know too; if I'm not quick enough in reading a notification, all I get is the little notification on the top bar and on clicking it, I can't always retreive the notification again. Used to be fine in my Hermes device.
