+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 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.

 facility. Fix it for clipped items. (#343, #4079, #2352, #432)

+This is the last release officially supporting C++03 and Visual Studio 2008/2010. (#4537)
+We expect that the next release will require a subset of the C++11 language (VS 2012~, GCC 4.8.1, Clang 3.3).
