Currently, if I have a dungeon with multiple rooms, every creature on that page is added to the turn tracker, unless I individually go into each one's menu and check/uncheck the "takes a turn" box.
It would be nice if there was a way to only add certain ones. The best way I imagine it would be to highlight a group, and then with them all highlighted, click the button. Then, perhaps have mechanism to add (In case the ruckus draws the attention of the guys in the next room) Maybe by clicking a + button and highlighting a new group.
