See only (Group)
As an ST of a game with 20+ players and 7+ groups, the game tends to look like a mess for me. While the players only see their own groups, I must watch them all, and it's common that one group has threads spread out over multiple pages.
It would be very helpful to be able to filter what groups you want to be visible. For example: By filtering "Show only Group 3" threads, all other threads should be invisible. It would make things much easier when trying to find a specific thread that's been buried by a dozen others.
