Scene Outliner
Scene Outliner is a separate dockable explorer pane. Use Window → Scene Outliner to show it, drag its tab to dock or float it, or use the pane's window button to open it in a separate window. Search filters the hierarchy while preserving parent nodes; arrow keys navigate and expand branches. The explorer follows the active template and selected layer, and works with standalone templates too. It shows the set's templates, compositions, layer hierarchy, data fields, media cues, asset definitions, and asset instances. Selecting an asset instance navigates to its owning layer when applicable. The first column shows Z-order, starting at 1; higher numbers appear in front. The eye column shows or hides an object. Component instance eyes control all their layers, and source-layer eyes edit the parent component, propagating to instances that inherit visibility. These changes support Undo.
