 If you are working on Dear ImGui codebase:
 
+### Metrics
+The Metrics window exposes lots of information about the library state.
+
+### Visual debugging
+You can use drawlist primitives on the foreground drawlist, e.g. `GetForegroundDrawList()->AddRectFilled(...)` to bypass clipping of the current window's drawlist.
+
 ### Logging
 You can use the `IMGUI_DEBUG_LOG` macro (declared in `imgui_internal.h`) to easily print text to the console while including the current frame counter, which is very often useful in log.
