Right, and the intelligence that the document should be deleted if
the last shell has been deleted should be in the document, not
in the shell. This will make the implementation something like:

Doc
  *views
  *shells
  *other_children
  removeView(view)   //called by the view in its destructor
  removeshell(shell) //called by the shell in its destructor
  createShell()

View
  *doc
  *shell

Shell
  *doc
  *views        // only child views
  createView()  // used for splitting only

Looks very good to me, but I only know the global setup of the datastruct.

The only thing worse than failure is the fear of trying something new
