 ## 2024-05-21 - Immediate Feedback in Native Apps
 **Learning:** In native applications (GLFW), state changes triggered by input callbacks often lack immediate visual feedback if the UI update is tied to a main loop timer.
 **Action:** Always call UI update functions directly from input callbacks for state toggles, rather than waiting for the next scheduled refresh.

+## 2024-05-22 - Safety Net for 3D Navigation
+**Learning:** In free-roam 3D applications, users can easily become disoriented. Providing a "Reset to Default" action significantly reduces frustration.
+**Action:** Always consider adding a "Reset Camera/View" shortcut in 3D navigation implementations.
