When selecting an object inside the selected Extension tab, it will appear in 2D or 3D in the preview below. The object in the view can be rotated by using the mouse buttons. You can also choose to minimize or maximize the preview window with the expand button in the upper right-hand corner of the preview window. This preview is optional and can be turned off from the Views tab in the Control Panel.

Collapse Extension tab fields

When scrolling through the contents of a tab, sections are automatically collapsed and expanded if all the tab contents do not fit at the same time. You can also collapse/expand sections by clicking the arrow next to the header. Collapsed sections will remain closed until expanded.

Navigating between Extension tabs

When you have many extensions installed, you may have more tabs than can fit on one screen. To scroll through all the tabs, hover your cursor over the list of icons and roll your scroll wheel. You can also left-click-and-drag on the icons to move them. 

To make tabs easier to find, you can select an Extension tab configuration from the drop-down menu at the top of the Extension tab area. This filters tabs to show only ones associated with the selected extension. Each extension has their own configuration, or you can create your own.
