So here's the situation. If I get a notification and I click it directly, that notification is erased and it no longer appears.
But...if I get 3 notifications for example, and I open all 3 in different tabs....They'll still stay there even though I've read all new notifications.
It's not a major problem of course, but I think it would be better if they were "erased" even if you open them in new tab and not just directly.
Just my opinion :)
