As far as I know, there is only one place where the 'Mark all post as read' function is available, which is the main board index.

Is it possible to insert this function into sub-forums? So instead of marking the whole board as read, I can mark sub-forums by sub-forums. Example: A 'Mark all post as read' function in Apple Byte. After surfing that section I click on that function and go on to other sub-forums, which later I can go back to the main board index and check whether there are any new posts in Apple Byte or not (indicated by the icon).

Cheers

here you go:

Oh bummer..haha thanks
