An overview at ../admin/reports/gitinfo of fundamental GIT info for all repos, from the project root to the deepest GIT directory it detects. It highlights what needs attention, in that case resulting in a warning.
It provides a quick insight for projects that contain one or more Git repositories. It is easier than searching for Git repos, then navigating to each of them in the terminal, and executing a long Git command for each piece of info.
Use cases
keep track of file changes in a development environment, especially when working with nested Git repos
audit a Drupal project for Git related issues
monitor the production server for changes outside version control.
Provides a button in CKEditor which, when clicked, will run the HTML_CodeSniffer Accessibility Auditor on the source code of the content currently in the editor.
