After a long playthrough, with all the different tasks, it can be difficult for a gamemaster to see which tasks have been completed, assigned, cancelled/failed etc.. Especially for new gamemasters who replace an older one.

I suggest adding an option which allows a gamemaster to switch to player tasks and briefing(as opposed to Zeus tasks and challenges)
Of course if a gamemaster is limited to a specific faction, he should only be able to see his own faction's tasks and briefing.
