I've recently fallen in love in WebStorm as an IDE for JavaScript development. The problem is, I come from a world of vim and lightweight editors, so I probably can't fully appreciate all the power that comes with IDE. Yes, I've seen the presentations and read the docs, but there's a lot of features and I'm not sure which of them are truly useful.
So, here goes my question: how do you use WebStorm and what do you find most useful? Any power-usage tips? Configuration hacks? Plugins worth mentioning?
I'm not looking for a list of features, I'm looking for a real-world usage examples and impressions.
PS. I work mostly with pure JS + Canvas element and some NodeJS.
