I am working on a Chrome Packaged App that sends notifications (which are now all hooked up). However, when the user is not in the app -- the app is in the background with other windows on top of it -- the notification pops up for a bit and disappears. I would like to change the taskbar icon to orange, the same that the Hangouts packaged app does, so that the user knows there is a notification to view at a later time.
I looked all though the notifications documentation and could not find any such feature, yet Hangouts is using it, and I believe I have seen it in other apps. Does anyone know how to trigger this in a Chrome Packaged App?
Thanks.
