Oh yea, looks great - just pops out and you and makes following the parens a lot easier - good job
I always wished plugins could take more advantage of the gutter icons; I had always assumed it was hard coded in there. And then I discovered you could redirect where ST2 looks for icons
. Even better, you could then use any icon.
Stuff like this will be helpful if other plugins are using gutter icons too, now you can distinguish them from each other, and they can even be more descriptive of why they are there by using an intuitive symbol, like a warning icon or whatever.
