The diff view is unusable if master has moved in the meanwhile. What you really need is a UI for "git range-diff".

You can do that in azure devops. By default, it shows all commits and then you can go to the commits tab and select the ones you want to view ( multiple or single)

Can it show a diff-of-diffs, and detect patches that were added, removed or reordered? Something like https://patchew.org/QEMU/[e-mail]....
