ExposeIt is a small Unity editor plugin that lets you expose anything into the Play Mode toolbar area — neatly wrapped in predefined or custom UI Toolkit elements.
No more cluttered context menus, no more temporary custom editors or nested inspectors. Just clean, instantly accessible buttons and fields right where you need them — in plain sight during Play Mode.
Unity 2022.3 LTS
The plugin relies on UI Toolkit-based play mode controls, which Unity adopted in this version. Tested with versions up to 6000.0.36f1.
- ✅ Unity Editor (main target)

Features available only within the Unity Editor.
You can declare a static element provider, which will be automatically discovered and injected into the Play Mode zone:
[PlayModeZoneElementProvider()]
public class CustomButtonProvider : IPlayModeZoneElementProviderThe IPlayModeZoneElementProvider interface allows you to choose between predefined elements or a fully custom VisualElement implementation.
⚠️ Note: Buttons do not persist across domain reloads, but will be re-injected automatically on[InitializeOnLoadMethod].
💡 See examples for usage.
This predefined element lets you display dynamic text that updates at a defined interval:
[PlayModeZoneElementProvider()]
public class PlayModeZoneExample4 : IPlayModeZoneUpdatableLabelProvider💡 See examples for usage.
Features available in both Editor and Runtime contexts.
You can add buttons to the Play Mode zone programmatically — useful for dynamic testing scenarios:
PlayModeZone.AddFunction("TestMe 0", () => Debug.Log($"testing method executed"));
PlayModeZone.AddOrReplaceFunction("TestMe 0", () => Debug.Log($"new impl on same button"));
PlayModeZone.RemoveFunction("TestMe 0");
⚠️ Note: You can't pass custom visual elements through this API — only simple hooks.
