On GUI Debugger

Requires Unity 2019 or later.

OnGUIDebugger enhances Unity’s legacy OnGUI workflow by providing a visual, interactive layout preview of GUILayout elements. Whether you're building custom inspectors, editor windows, or runtime debug panels, this tool helps you understand how your GUI components are arranged and interact.

Key features include:

• Real-time rendering of GUILayout elements such as Labels, Buttons, Toggles, Sliders, and Fields.
• Interactive preview windows for both Editor and runtime contexts.
• Clear separation of layout containers for easier debugging.
• Minimal setup—just drop in and start visualizing.

This extension is ideal for developers who still rely on OnGUI for editor tooling or runtime overlays and want a faster, clearer way to debug layout behavior.
