While the Advanced Scene Switcher occasionally breaks down, I've seen bugs get worked out with updated patches. My favorite feature is the SceneSequence tab.
This effectively allows the operator to create macros for timed transitions. That may sound like a simple thing, but it saves loads of time and circumvents user error for pre-timed things like commercial breaks and rapid-fire round trips across multiple scenes.
Would LOVE to see this gain official support and supplant the default Scene Switcher.
