Sorry this hasn't been added yet.  I'll make it a priority for the next version.

I find when I'm scrolling or searching through a series of subroutines (could be dozens) in a file, it is not always clear which subroutine or function is being searched or revised.  To help reduce inadvertent errors in search/replace and editing code, it would be useful for SF to Highlight the subroutine or function in the project File Outline list so it's clear where you are in a lengthy file containing dozens of subs and functions.
