a vertical navigation bar (left), allowing you to navigate through each of the Quanta modules (User journeys, "System", "Real User Monitoring"etc.).
a site selector (top left), allowing a user with access to multiple sites in Quanta (e.g. using Quanta with an Enterprise license, using Quanta by an agency with access to multiple clients Quanta accounts, etc.) to switch between sites. When using Quanta in multi-site mode, it is also possible to compare performance data by selecting multiple sites at the same time, or to build a custom dashboard with metrics from multiple sites.
a time period selector (top right), which allows you to change the period being analysed at any time. This feature is important to see the evolution of a site's response times, sometimes over several weeks or months. By default, Quanta shows the last 24 hours and refreshes the page every minute to show the latest measurements in real time.
