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
