Photos taken moments apart that look alike are stacked (the tiles with a number). Open a stack to compare its shots side by side and keep the best one(s). Drag Stacking left for tighter stacks, or use Unstack to see every photo on its own.
Rounds. Everything you pick moves on to the next round, where only those photos are shown so you can narrow them down again. Switch rounds with the tabs at the top, or open the next round in its own window — both windows stay in sync, so you can go back and forth. Changing a pick in an earlier round updates the later ones.
