Gnome developers decided that users should be given more fine-grained control over what notifications are displayed by the shell, so they are planning to enrich the gnome control center with a per-application filtering tool. The following is just tentative design (experimental-nothing is sure yet):
As you can see, the plan is to also give the Lock Screen attention as the notifications now appear there too! These are the objectives in detail:
- Global system notification settings
- Per application notification visibility
- Per application notification visibility at the lock screen
- Provide a place to undo hiding conversations
Extensions like this one, prove that this was something really needed by everyone. Gnome Shell 3.8 users, will be able to easily “tame” one of its biggest powers that is the notification system.
