title: Is there a way to highlight git changed line in Intellij
body: <p>I have a big configuration file in IntelliJ which I am editing. </p>
  
  <p><strong>Is it possible to highlight the lines that I changed, in a way similar to a git diff directly in the editor?</strong></p>
  
  <p>Note that I am aware that IntelliJ shows the changed lines on the side of the editor (nice feature btw!). Here I am however looking for something more prominent, that would highlight the changed lines (eg by changing the background color) directly in the editor. The motivation is to enable to spot exactly what line was already changed while editing the file. </p>
