Maintaining visibility of objects that were not initially visible

I’m sorry, but I can’t seem to follow. I do have each menu item at the top level, so they are there all the time but they are not initially visible. I don’t know what you mean by “control everything from the top.”

I already have variables that keep track of which pages have been visited, so I can use those to test whether a menu button should be visible. I just can’t seem to get actions that are in a chapter to display the buttons when you are in a different chapter. For example, even though buttons for chapter 1 have been made visible by actions in that chapter, when you go to chapter 2, the chapter 1 buttons become invisible again.

Could you explain in more detail what you mean by controlling everything from the top?
