We've updated our Sidebar navigation so your Sleuth experience is calmer and more focused. The slimmed down navigation allows you to quickly navigate to your top tasks; discovering your Organizations/Projects metrics and status.
Clicking through 'More' will still allow you to navigate to individual deployments and impacts. The navigation automatically expands and contracts to show your navigation context while you move through Sleuth and it remembers your last state, just in case you want to roll with the nav fully expanded.
