What do you mean by manage, do you mean from an architectural perspective as in which classes control
the view stack index, calling remote services and so forth. Or do you mean from a UI/UX perspective, meaning how the application flows and
appears to the user ?
Well, Like you have a application like Microsoft Word for example... all the menu's and options are always on the same position. But all the changes appear in the main screen... so if your writing a simple text you just type, but if you are typing some text on a envelope, the main view changes.
Man this is so hard to explain... basicly its how you manage all the custom components in the center screen without changing all the default menu's around it.
My english sucks at the moment... just woke up
Well, what is your first language than ???
What you are looking for I think is to work with modules or Stages which work within one module but not the other !
