Picture this. You are just walking around Scratch and you get a notification. You actually feel quite cool for a while and you click the envelope. The moment you click it, you get a notification saying there was new activity in some crappy studio that you don't even own, and all hope is lost.
Yes, that happens to me every day and yes, that is why we have to team up to remove Studio Activity from the Scratch Notifications section!
Scratch Team, if you really want to inform Scratchers about new activity in studios they curate, why don't you make a separate button for all notifications on Studio Activity and as a bonus, one for notifications on Following Scratchers' Activity so you know what they're up to?
Let's get this message to spread all across Scratch!
