Allow scrolling through diff file, also the unchanged parts, for easier context searching
I often find myself wanting more context around a diff files highlighted lines.
For example, in gitlab-com/www-gitlab-com!2297 (diffs) there is an edit in line 214, but I happen to recall that this topic is also addressed earlier in the file. How did I know it was line 69? Well, I went to atom, looked for the topic in the file, noted the line number, and came back to make the comment in the merge request.
What I would have preferred to be able to do, is just scroll up in the diff file itself. I could click on "view file", or "edit", but that is an extra click, a different environment, and it would not show the diff highlighting which is valuable.
I imagine this may be useful in reviewing code as well, not just text for a website... but I will let others be the judge of that :-)
