The ability to edit turn order would be nice - though if you only need it to force a player to skip his turn, applying the "Tripping" debuff to the character would be an adequate workaround.
Often times the characters asked for special checks and weren't penalized with any AP cost too. The GM needs a way to lower the AP of a player who attempted a special "off the books" action during combat.
The guy who passed his turn simply pooled those action points towards his next turn.
