According to Allan Day, another area of the Notification applet that needs to be improved is the quality of the notifications displayed there. For example, the applet should no longer display notifications for events that are not of interest to the user, nor those pesky, sticky notifications. Check out the attached mockup for details on that. Therefore, the plan for the upcoming GNOME 3.24 desktop environment, due for release on March 22, 2017, is for the Notification applet to get a UI revamp that will display only notifications from various apps that are of interest to the user and reject notifications after a period of time if they are read.
