What's the URL of the page this enhancement relates to, if any?


Describe the enhancement and the motivation for it.

Sometimes a user posts a review that is a large refactor, with code blocks moving around quite a bit. In these cases, it is hard to understand the new code by looking at the diff.

I'd rather just see the new code (without reference to the old code). This sounds like I should just download and apply the diff, however there are two killer features of RB that I would like to have available. I'd like to see only the modified lines, and I'd like to be able to comment on the code.

What operating system are you using? What browser?

Linux, MacOS. Chrome.
