Our Display Git Status plugin has just been approved on the WordPress.org plugin marketplace
Display Git Status is a utility plugin to provide basic git status information right in the WordPress admin bar.
We have created this plugin as a complimentary and free plugin for our users. Given our service offers Git source controlled plugin and theme updates. It's obvious such a feature would be beneficial right within the admin area. And we were surprised there wasn't already a solution.
This plugin is great as a gentle reminder or flag to see if your staging or even production site becomes out of sync with your repository.
Once activated just look out for the admin bar icon link turning to a red background, which indicates there are changes you probably need to investigate.
We have added a new page to the documentation for our plugin (soon to be plugins) here.
