elis, I think you got where I am coming from. If something like this was going to work, this is the way I think it would need to be done. I like the demo site you posted up. The UI looks nice, and good be tailored to Sublime Settings very nice.
In general, with a nice front end like that, and UI mapping included in the plugin, I imagine it could go fairly smoothly. Really, all we would need now, is clearly defined specifications for the UI mapping, and the will to do it.
