Window managers are one of the hacker's secrets to increased productivity. Manually managing windows takes small but real amounts of concentration away from more important matters. Over time that adds up. Window managers relieve you of that by doing all the moving and positioning for you.
Most window managers give you pre-designed hotkeys that move windows in simplistic, often unhelpful ways. They don't adapt to your preferences or your behavior. Autumn puts the control back in your hands, by allowing you to shape your very own customized window manager through experimentation.
Autumn comes with everything you need built-in, including a state-of-the-art IDE, embedded searchable documentation, and a developer console, so you can explore all that Autumn can do for you with complete ease, and experiment without losing your place or your train of thought.
