Github user 1ambda commented on the issue: https://github.com/apache/zeppelin/pull/2506 The one of famous product what does the same thing with this PR is Source Tree as u know. And it has this kind of UI. I think @tinkoff-dwh you can get ideas from this UI  - you can see the whole commit list and scroll down to navigate more. - if you click one commit, automatically display the diff between prev commit - if you want to compare to separate commits explicit, you can select the commits for comparison.
