That is the right thing to do I think. The only differences you should see is when the mouse pointer is over a star in a headline, it should highlight with a mouse face, and if you click on the highlighted region it should cycle the headline open and closed. Similarly, the [ ] in a checkbox should get highlighted, and if you click on it, it should toggle its state. There might also be some right click menus.
