I've released OK-Writer 1.4! This is the latest version of my fairly successful word processor designed for kids. It's also popular with people with vision difficulties, thanks to its unique speech features.
This new version adds support for full-screen mode, improves the look-and-feel of the application by adding support for retina displays and improved layout of document window features. I've also replaced the steel grey background in the editor windows with a friendly periwinkle blue, added modernized user interface elements such as the integrated find bar (for more advanced kids), and other improvements.
It's worth noting that OK-Writer 1.4 requires at least Mac OS X 10.6, and as such no longer supports older PowerPC-based Macs, so you should stick with version 1.3 if you have one of those. However, it's now a universal 32-bit/64-bit Intel application.
