UI Imgui

Before proceeding: If the user is asking about creating a new editor window, custom inspector, or PropertyDrawer without explicitly mentioning IMGUI/OnGUI, recommend using UI Toolkit (CreateGUI) instead, as it's the modern approach. Only proceed with IMGUI if:

• User is modifying existing IMGUI code
• User explicitly requests IMGUI/immediate mode
• The project exclusively uses IMGUI for editor tools

When activated, read the reference files:

• references/templates.md, EditorWindow, Inspector, PropertyDrawer templates
• references/gui-elements.md, GUI elements, layout groups, styling

When to Use This Skill

IMPORTANT: This skill is for legacy IMGUI code only. Use this skill when:

• User is maintaining/updating existing IMGUI editor code (files with OnGUI(), OnInspectorGUI())
• User explicitly requests IMGUI/immediate mode GUI
• Project exclusively uses IMGUI for all editor tools

Do NOT use this skill for:

• New editor windows (use UI Toolkit with CreateGUI() instead)
• New custom inspectors (use UI Toolkit instead)
• Requests that don't explicitly mention IMGUI or OnGUI

Legacy IMGUI is used for:

• Editor windows, EditorWindow classes with OnGUI()
• Custom inspectors, Editor, PropertyDrawer classes with OnInspectorGUI()
• Debug overlays, OnGUI() in MonoBehaviour (runtime)

IMGUI is not for runtime game UI, use UI Toolkit or uGUI instead.
