DevPanel: A New Gem That Provides Page Render Times and Debugging Info In The Browser for Rails Apps
DevPanel was created after reading about StackOverflow developers having the ability to see page render times in browser, in an easy and convient manner. DevPanel is a small box that appears on your screen that shows all sorts of debugging info. See render times, including time spent in the view and controller as well as the number of partials that were rendered. It also shows which controller was called and which action was rendered which is useful when you are new to an app and it's not clear what page is being loaded when you click through the app. Check it out!
