One new feature is control over visibility of completed proofs, -@xref{Visibility of completed proofs}. +@xref{Visibility of completed proofs}. Another new feature is the +tracking of theorem dependencies inside Isabelle. A context-sensitive +menu (right-button on proof scripts) provides facility for browsing the +ancestors and child theorems of a theorem, and highlighting them. The +idea of this feature is that it can help you untangle and rearrange big +proof scripts, by seeing which parts are interdependent. The implementation +is provisional and not documented yet in the body of this manual. It only +works for the "classic" version of Isabelle99-2.
