All of my friends have been confused by the recent notifications, because once you miss an invite, you need to open notifactions, and then click on the notification in THAT list to display it.

e.g.

"Kalist invited you to join anormal game." <- you click this line to show the invite again

Suggestion ---- put a small "[ACCEPT]" button at the end of the line

like this
"Kalist invited you to join a normal game. [ACCEPT] [DECLINE]"

more intuitive and saves a click

Good one, thanks.
