or by calling the ShowStackToolWindow() function. The tool run queries on hovered id to display
details about individual components that were hashed to create an ID. It helps understanding
the ID stack system and debugging potential ID collisions. (#4631) [@ocornut, @rokups]

-Dear ImGui internally need to uniquely identify UI elements.
+Dear ImGui internally needs to uniquely identify UI elements.
Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
Interactive widgets (such as calls to Button buttons) need a unique ID.
-Unique ID are used internally to track active widgets and occasionally associate state to widgets.
-Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.

+Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.**
+
+Since Dear ImGui 1.85 you can use `Demo>Tools>Stack Tool` or call `ImGui::ShowStackToolWindow()`. The tool display intermediate values leading to the creation of a unique ID, making things easier to debug and understand.

- Unique ID are often derived from a string label and at minimum scoped within their host window:
