The initial release is basically a hierarchical wordbook with sounds. But we'd love to add extra features, any code commits are more than welcome, especially considering that we wont have any development time in the nearish future.
There're some screenshots on the wiki if you don't want to build it. http://wiki.github.com/koudelka/TomBoy
When I get a chunk of free time, I'm going to submit it to the App Store. But in the meantime, if you know anyone that could use it, please pass it on.

Thanks!
P.S. Shameless plug: Jess is looking for work! http://jessicaobrienart.blogspot.com
