Built from the same core as Nisus Writer Express, Nisus Writer Pro adds new features while keeping the familiar look and feel that has won praise from users and the press alike. Nisus Writer Pro brings new features such as Table of Contents, Indexing, Bookmarks, Widow and Orphan control, Cross References, Line Numbering, and Text Wrap around images.

Familiar Classic features are also on board, like attribute sensitive Find and Replace, an upgraded Nisus Macro Language, and Glossaries. Original features have also been significantly improved.
