Improvement for easier review

There are times that we have many pull requests. We make a comment and create a task and then the developer will update the PR later. When we come back to check the changes they made, we normally can't remember what changes we asked for exactly. This is a large scale application and with so many developers.

So if the file we commented is changed, we no longer can see the comment or the task unless you go to 'Activity' tab which only shows you the outdated code. We need to have 2 window side by side one with outdated code and the other with the new code to compare.

I wish we could see what file we made the comment and or created task against in the top where the changed files are listed as part of that PR.

Then by just clicking the button in front of the file, that we created task for, we could see both outdated one from the activity and the new one side-by-side.

The current side-by-side difference only shows the difference with the target branch to be merged in not with the previous commit

I know it is very hard to find what line of code we made comment against to display that as the new commit may have radically changed the file but displaying the whole file including the comment/task we created is possible.
