### Description Add ability to specify directory when comparing objects ### Documentation blurb #### Overview Since `git diff` allows you to narrow results to certain directory (`git diff tag1..tag2 -- specific/folder`) it would be nice to have such possibility in Gitlab #### Use cases Imagine you have big repo with several logic projects in it (monorepo). Let's say `foo` is one of the projects located in `packages/foo`. If you open `/compare/foo@3.6.5...foo@3.6.6` you want to see the changes narrowed to certain directory (`packages/foo` in our case) ### Feature checklist Make sure these are completed before closing the issue, with a link to the relevant commit. - [ ] [Feature assurance](https://about.gitlab.com/handbook/product/#feature-assurance) - [ ] Documentation - [ ] Added to [features.yml](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/features.yml)
