I wouldn’t want to switch to Scope Context Coloring exclusively and give up syntax highlighting. I’ve been thinking of a toggle between the two but even that seemed cumbersome when something like code coloring should be automatic and without developer involvement. And then David Li had the most brilliant idea of using opacity instead of color for scope. Syntax Coloring coupled with Scope Context Opacity gives us both, without choosing which at which time, and also helps by keeping the current scope more in our attention focus. It reminds me of iA’s Writer which remove all the visual clutter to help you focus on the current thought.
As far as I know this doesn’t exist yet, at least not for Sublime Text 2. A perfect excuse to dust off some Python coding chops!
