I added the third working application to Om’s WebOS. The Nature app contains three daily environmental challenges that users can complete using checkboxes. JavaScript counts the checked challenges and updates the progress message automatically. I also added a reset button that clears every challenge. The app reuses the window system I previously created, so it can open from the desktop, move aorund the screen, minimize to the taskbar, maximize, restore, and close. This helped me understand how one reusable window system can support multiple applications without writing separate window code for each one.
