 ### Visual debugging
 
-You can use ImDrawList primitives on the foreground drawlist, e.g. `GetForegroundDrawList()->AddRectFilled(...)` to bypass clipping of the current window. Whenever you are working with coordinates, consider displaying it on screen using `AddRect()`, `AddCircle()`, etc.
+- `ImGui::DebugDrawCursorPos()`, `ImGui::DebugDrawItemRect()` are a convenient way to easily display the current layout position or previous item geometry.
