I've really gotten into Sublime after being 100% text-editor for perl, HTML, javascript and PHP for years and years. Can anyone tell me why I should switch to this IDE? What am I missing out on? Many of the 'smarts' seem dependent on writing code in a particular way (eg, using PHPdoc) or following their file naming conventions. I'm eager to try anything that's better. But I'm not getting it.
