The Features pane displays all features that are available on the camera that is selected in the camera selector. It also contains the User Level drop-down list where you can select your level of expertise. The available options are Beginner, Expert, and Guru. At the beginner level, the Features pane will only display the most basic camera settings. At the expert level, the Features pane will display the most commonly used camera settings. At the guru level, the Features pane will display all camera features, including the most advanced ones.

You can place the features you use most often in the Favorites category. This allows you quick access and avoids having to navigate the feature tree. Adding a feature to the favorites doesn't remove it from its original category in the feature tree. The favorites remain in place when you close the blaze Viewer.

In the Features pane, you can also select whether to automatically poll the camera in regular intervals for updated parameter values. Alternatively, you can click the Refresh button to refresh the features list manually.
