-This sample demonstrates how to use the Input System APIs to set up a rebinding UI. The main file is [RebindActionUI](./RebindActionUI.cs) which, aside from serving as an example, contains a reusable `MonoBehaviour` component for composing rebinding UIs. The [RebindUIPrefab](./RebindUIPrefab.prefab) contains a ready-made prefab that can be used as a simple drop-in setup for rebinding an individual action.

-Finally, the [RebindSaveLoad](./RebindSaveLoad.cs) script demonstrates how to persist user rebinds in `PlayerPrefs` and how to restore them from there.
+[InputActionIndicator](./InputActionIndicator.cs) and [InputActionIndicator.prefab](./InputActionIndicator.prefab) 
+shows how to make a simple UI indicator that shows whether an associated input action is enabled, disabled or 
+performed. This behavior has been added to this sample to add observability of actions triggered within gameplay, 
+menu and rebind contexts.
 
-In this sample, keyboard bindings for "Move" (default WASD) is rebound as a single composite. This means that indivudual parts will get assigned one after
-the other. Another way of doing this is to set it up as four individual button bindings and assign them individually as four partial bindings.

-In this sample it is possible to directly rebind gamepad sticks in the gamepad control scheme. In practice, you probably
-don't want to set up rebinding the sticks like this but rather have a "swap sticks" kind of toggle instead. In this
-sample we have both variants for demonstration purposes.
