Ever tired of constantly getting notifications for threads, but don't want to unsubscribe cos' you want to keep track of them? Get tired of constantly clickin' that notification just to leave the tab and have it come back two seconds later?
Well, this is the suggestion for you.

I'm suggesting a mute feature. Maybe the button can be somewhere near the 'Clear all notifications' button, or by the 'unsubscribe' button. This would be for muting specific threads, or all of them. Mute button could also be besides the subscribe button as well.

I think this would benefit to those who follow a lot of art threads, or even just active thread's they want to keep track of w/out having to unsubscribe purely to lose the notification. :0
