This utility plugin changes the theme of the current user to Sunrise, and uses the Sunrise color scheme when browsing the front-end, to help ensure you are viewing and editing the Development Site when making crucial changes to a site.
This plugin also adds a menu item to the admin bar to further confirm that you are on the Development Site.

Active Plugins

So I had this plugin installed in my multisite, but had it deactivated. (Obviously, you don’t need a tool like this active all the time.)
Today I wanted to check on a couple of plugins whether they were still active anywhere in my multisite, so I remembered Active Plugins. Cautiously checked the plugin details first and saw the warning about tested only up to WordPress 3.whatever.
So I tested activation on my staging site first, no problems in debug mode.
Then I activated it on my production site, and it delivered just as always.
I understand and appreciate the author’s warning in the description regarding tested compatibility, but I’m happy to share for me this precious little helper still works like a charm in a productive WordPress 4.4.1 multisite environment. 
Quality code always wins. Chapeau @trepmal! 🎩



Still works with WordPress 4.4.1, tremendously handy when in need
