Hi,
I have some dude about notification system.
When have some notification in my user panel go to review. Click on it and go to the thread to view. This is ok but then I need to go other more time to notification option and click in the icon "mark all as read" to delete the notification number.
In other system forum when you go via notification panel and click to go to the thread the system detect that you have already seen the notification and automatically delete the notification number, not need to go to click in "mark all as read".
