While running for PFs today, I learned that a really nice but small QoL thing would be for the PF to not keep the roles of the players that leave your PF. For example, if I have unrestricted roles, but a SAM leaves my PF, the empty roles will still be unrestricted except for that slot the SAM occupied. Every time that happens, I have to edit the PF then select then deselect the box to remove class restrictions. This happens for both when the roles are role-specific and unrestricted.
