The AEM Developer Chrome Extension is a very helpful and elegant add-on to Chrome to make our lives developing within AEM easier. Nate Yolles created this little gem. It reduces the friction for common tasks.
Switch WCM modes. Toggle from TouchUI to Classic. List links to all AEM servers. Toggle debug. Clear cache and memory. Open the Marketing Cloud Debugger. These are all tasks that are part of of the every day grind. This extension reduces the steps to do each one greatly.
