Nisus Software has released, a new word processor based on their earlier product, Nisus Writer Express (which remains available). Nisus Writer Pro adds numerous features that appeared in Nisus Writer Classic but hadn't yet been seen in a native Mac OS X version of the program. Nisus Writer Pro can perform attribute-sensitive find and replace operations (both manually and in macros) and expand glossary entries on the fly (somewhat like Word's AutoCorrect feature). Other newly added (or "restored," if you prefer) features include tables of contents, indexing, cross-references, bookmarks, text wrap around images, widow and orphan control, multi-page footnotes, line numbering, and an expanded macro language.
Nisus Writer Pro costs $79, or $99 for a three-license Family Pack; single upgrades from Nisus Writer Express are $45. (Prices for Nisus Writer Express have been reduced to $45 for single users and $79 for Family Packs.) Nisus Writer Pro is a 103 MB download; a 15-day free trial version is available.
