Refine the "required actions"
As far as I know, 2 referee reports are sufficient during review. During the second round of review I have commonly encountered a situation, where I would invite the referees from the first round and they would immediately accept. At the same time editorial view of the submission would insist that I need to invite at least 3 referees.
I therefore propose to consider the number of referees that accepted the invitation in determining whether there are pending actions.
