Guided diff tour now in Beta

Large diffs are hard to review because there's no natural order to follow. Guided diff tour groups related files into sections, orders them into a suggested reading path, and adds short explanations so you can review quicker and with more confidence.

To use it, open a diff in Sourcegraph and switch from Changes to Tour. You can get there from the repository Compare page, from the Branches tab when comparing branches, and from commit pages. On GitHub, you can open the same diff in Sourcegraph with the Sourcegraph Chrome extension.

The tour is designed to be read from top to bottom. It surfaces the files it identifies as most important first, then groups the rest of the change into sections so you can follow the intent of the diff in a clear order instead of jumping around the file list.

You can mark files as viewed as you work through the tour and track progress across the diff. Tours are also cached, so they only need to be generated once and other reviewers can open the same diff with the cached result.
