I like a lot of the minor tools that I don't use often, but come in handy when I need them.

Avy Mode, which I suppose is the successor to Jump Mode. Letters light up across the buffer and you can quickly navigate to where you want.

Multi-cursor mode. A Sublime killer feature. Wasn't exclusive very long.

Not sure what it's called, but it binds window changing to shift arrow. Probably my best time-saver.
