Users then have several options, none of which are practical: * Use `git diff` manually * Download the 'plain diff' that GitLab offers * Download the 'patches' that GitLab offers As a solution, I think it should be possible to **hide certain files** - 'making way' for relevant files. Note that this is NOT a duplicate of https://gitlab.com/gitlab-org/gitlab/-/issues/17647; collapsed files still count towards the max amount of files shown. Files to hide could be specified using `.gitattributes` (as is the case for collapsing). Although the contents of hidden files may not be relevant, it should be evident that there are hidden files, to prevent 'XZ Utils'-like ordeals (injecting code in hidden binaries). <!-- Label reminders Use the following resources to find the appropriate labels: - Use only one tier label choosing the lowest tier this is intended for - https://gitlab.com/gitlab-org/gitlab/-/labels - https://about.gitlab.com/handbook/product/categories/features/ -->
