The Initiative Tracker allows you to keep track of turns. Show the initiative trail to players by clicking on "Show initiative", then add elements to the trail by right-clicking on Board Sprites and clicking on "Add turn".
Change the order
Drag and drop elements to reorder them as you need.
Tracking similar Sprites
Hovering on an initiative element will highlight it on the Board, handy when you're using the same Sprite for multiple ennemies.
