action of buttons "ungraded" / "previous" / "next" / "ungraded" is strange and confusing
In my instance TN3155, it seems that pushing the buttons next / previous do not make any sense
I start on a new question, I get an question to grade. I grade everything and I click "next" / "right ungraded". Nothing happens. Then I push the other ones, and I seem to need to go backwards to go to the next student question answer I need to grade?
Shortcut seem strange too? Why the asymmetry in shift?
I'm not yet a heavy user myself, I don't know if this is normal behaviour.
