+1. Unfortunately there are many existing codebases where tab size != indent size, and as-is, Sublime makes a mess of these files.

I see all of these on a regular basis:

A. Indent is 2 or 4 columns, no hard tabs allowed

B. Indent is 2 or 4 columns (mixed tabs and spaces), hard tabs are 8 spaces (common on Unix)

C. Indent is one hard tab, hard tab is 4 spaces (common on Windows)

D. Indent is one hard tab, make it whatever size you want

(Regardless of what the style "should" be, requesting that an entire project change their indentation because my editor doesn't support it has not gone over well in the past.)

Any word on when/whether this is likely to get implemented?
