Close, but not close enough.

I use JSON config files for various purposes, and need to be able to edit quickly in the raw format. Its extremely helpful to have two editor features that this editor lacks. One is syntax highlighting, making keys and values different colors and making text a different color from punctuation makes the JSON structure much easier to see. The other highly useful feature is error highlighting and positioning. Its great that this editor detects errors and tells you what they are. It would be much, much better to highlight that error in the raw text and scroll the window to it. Bonus points for making the highlight pluse three times. :)
