Can anyone point me in the direction of some good desktop web app design patterns for important alerts. The alerts should be accessible where ever you are within the app, as the status of the alert may change. I need something that will not be missed by the user.
I don’t have specific examples but have you looked at the Notifications Web API? That could be an option for you. Using the notifications web API is dependent on the user accepting the notifications prompt first.
Another idea is to implement your own notifications system. In your case, you could present those notifications differently based on severity.
Thanks! That looks like a really good resource!
