The Outliner 2.0 is a fast and easy to use scene management tool. It has a wide range of features, including selecting, hiding, freezing, linking and grouping objects in the "Hierarchy Mode". In the "Layer Mode" you can organize your scene by dragging&dropping objects from one layer to the other. What's more, the Outliner offers support for nested layers, to manage scenes more efficiently. The interface is nimble enough to keep it open constantly.
