Google Chrome has a ton of apps and extensions, but it is tough to maintain them in Chrome. SimpelExtManager is a simple extension which maintains all your existing extensions in a easily accessible way.
After installation it sits in your toolbar and provides all your extensions as a list. You can disable them with a check box, or you can uninstall them. You can create extensions as groups to arrange and maintain them easily. Overall, it’s a pretty useful extension for convenient to access all apps and extensions in one click.
