Activity favorites really need improvements, I agree. I’ve suggested many ways to do so but haven’t succeed to convince the team. Here’s my last attempt about it: https://github.com/buddypress/buddypress/pull/238
I’m not sure what you call “Notification” is an item of the Notifications component, as you can always mark as read notifications going into the corresponding profile page.
I guess what you call “Notification” is the amount of favorited activity that is added to nav items.
We’re aware of the issue but haven’t found the best way to deal with it.
