Hierarchy Designer

Hierarchy Designer is a lightweight, editor-only tool that upgrades your Unity Hierarchy window—making it cleaner, more customizable, and far easier to navigate.

With no DLLs, no extra GameObjects, and no intrusive changes, it integrates seamlessly into your workflow. Whether you're organizing a large scene or just want a visually tidy Hierarchy, Hierarchy Designer gives you the tools to make it yours.
