## Problem to solve After opening a merge request and viewing the diff, it isn't possible to switch to a commit by commit revision without first going to the commits tab to select a commit. Even then, every time I want to change to a specific commit I need to go the commits tab. Also, when I want to switch back to see the combined diff there is no easy way to do this. ## Further details Review Board has a slider interface for the reviewer/reviewee to diff between review rounds by sliding back and forth in time. Specifically, if you participated in a few rounds and then jump in later, you can see what’s new without cluttering with the old. | Version 0 (merge base) to Version 2 (`HEAD`) | Version 1 to Version 2 (`HEAD`) | | --- | --- | |  |  | ## Proposal Improve the interface of our revision and commit selection interface in the merge request. ## What does success look like, and how can we measure that? (If no way to measure success, link to an issue that will implement a way to measure this) ## Links / references - ReviewBoard demo: http://demo.reviewboard.org/r/5/diff/1-2
