Scope coloring was first suggested by Douglas Crockford. So far the only plugin for Sublime Text 2 (that I know of) that implements scope coloring has been made solely for JavaScript at https://github.com/mazurov/sublime-levels .

It would be great if this feature could be implemented for all languages, especially Clojure and Scheme (for me).

Difference between scope coloring and syntax highlighting:

I think it'd be beneficial if there were a new option for draw_white_space that only draws white space on the left most and right most edges of a line so any single white spaces between words or characters in the middle of lines are ignored. Similar to setting editor.RenderWhiteSpace to "boundary" in VS Code. So it'd appear:

def function():
••••if True:
••••••••print("I <3 ST")
••••else:
••••••••print("I'm aware there's trailing white space on this line")••

More often than not, seeing white space helps with indentation, so having any source code being viewed decluttered with potentially unnecessary information while still maintaining its usefulness would be a win-win.

Let's say the width of a monospaced letter is 1em - allow users to configure the leading space width so that we can have the benefits of tabs while pacifying the classless naysayers of space town ;)

leading_space_width: 1.3em     ### or just 1.3

It’s simply a large and translucent message that’s displayed over the contents of your screen. They fade away when the user takes any action (like typing or moving the mouse). In practice, the message is both noticeable yet unobtrusive. And because the message is transparent, you can see what’s beneath
