The Properties tab displays along the right edge of the Dependency Viewer tab, and remains displayed as long as the pointer is over the Properties roll-out tab. Move the pointer away and the tab is hidden again.
To dock the Properties tab, pause the pointer over the Properties roll-out tab, and then while the tab is displayed, click the Auto Hide (push-pin) icon in the upper-right corner of the tab.
The Properties tab is docked along the right edge of the Dependency Viewer tab. Notice the Search and Block Filter tabs are also now docked, behind the Properties tab.
