"Lightroom Dashboard is a new browser-based app that helps you visualize your Lightroom catalog data and surface interesting details about your personal photography habits. To get started in using the service, all you need to do is drag and drop your catalog into your browser.
"The catalog is read by your browser without being uploaded to any server. It’s all 100% free, and there’s no software to download and no plugins to install.
