Notification pop-up

[zytegalaxy]

Notification pop-up UI is almost the same as the notification layout shown on the list of notifications, except it does not have the side scroll bar for going through the list. The back button for the pop-up should clear it and show the previous view (i.e. last view should be remembered).

Delete will have the same effect as back, except it will remove it from the notification list also.

Apps should be able to show notifications on the GUI using JSON RPC. We can apply the same logic to show a prompt instead of notification. The difference would be that prompt returns a result (user input) where as notification just displays information.
