CYOI lets you pop out editors from the Inspector window into a completely separate window. They’ll stay open until you close them, or when the object is destroyed. Multiple editors from multiple Objects and assets can be open at the same time. Build it however you like!

Choose to visit Choose Your Own Inspector’s Asset Store page

Features

• Works with Component editors and Asset Importer editors

• Collapse individual editors and containers of editors (for Component editors only)
• Add as many editors as you need with no artificial limitations
• Close editors and containers as you complete your work to keep your workspace clean
