### Problem to solve Sometimes when working on a project via the Web IDE this is done via a fork. If the project was forked at a previous point at time, it may have become out of date with the upstream project. This would make working in the project harder as changes may not be compatible. ### Intended users <!-- Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later. Personas can be found at https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/ --> Anyone who contributes to other projects via a forking workflow. ### Proposal <!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey --> The Web IDE should provide a button to fetch changes from upstream in a forked project. This would update the existing fork so that the user could continue contributing to the project. ### Links / references https://gitlab.com/gitlab-org/gitlab-ce/issues/64040#note_189430871
