SubHierarchy is a Scene Hierarchy toolkit for keeping big scenes readable.

• Hierarchy Colour: Tint objects (and optionally their children) with presets or a custom colour so related items stand out.
• Tree: Collapse All or Expand All to tidy or open the whole hierarchy in one click.
• Reorganise: Sort Alphabetically or Sort by Colour to group and order the hierarchy.
• Visibility: Hide All, Show All, or Isolate Selection (selected object and all of its children).
