Breadcrumb Bar
When navigating between different editors within the scene, the breadcrumb bar will always show you what you are currently editing within the scene, and give you the ability to go back. The breadcrumb bar can be found between the editor document and the render preview.
Here is an example, a binding to a layer setting is being edited within a scene.
Interactions
Here are some basic interactions that are available within the breadcrumb bar.
Open Parent
Click on one of the parent breadcrumbs to navigate hierarchically back within the scene. Navigation will automatically continue upwards, until a breadcrumb has been reached that can be opened.
Open Neighbor
You can switch to a neighboring breadcrumb by clicking on the dropdown icon of the first parent and clicking on the neighboring breadcrumb you would like to open.
