I am wondering if I can turn on a quick diff feature in RubyMine. By default, in Netbeans, you see a green, blue or red bar on the left of the normal editor that shows what has been added/modified/deleted relative to the previous revision (Git or SVN).
You can also turn this option in eclipse.
Does it is exist in RubyMine?
To illustrate, On this image, you can see added code (green) and modified code (green) as a quick diff :
