Q:

SSMS - Is there a way to highlight changes since last save?

An example: 

If I was to have some code such as, SELECT * FROM Table1, and I then saved the script.
I then changed it to: 

SELECT * FROM Table2 
SELECT * FROM View1
SELECT Column1 FROM Table1

Then is there a way to highlight, within SSMS, the parts of the script that have changed since I last saved?

A:

Nothing to highlight parts of the script itself from what I can tell.
The closest thing that is already in SSMS is:

Tools
Options...
Environment
  
Font and Colors
  
Display Items:
  
Track Changes after save
Track Changes before save

This vertical bar on the left hand side of the script page already exists. I've just changed the colors to make it more visible so I can make better use of it.
Not what I was looking for, but it will suffice.
