One of my favorite tools for research and multi-section writing just got better. Lion compatible and support for ePub exports are just two highlights of this update. It’s also cheaper than it was when I purchased it, now just $19.99 in the Mac App Store — it’s a bargain. ((Or it could have been free if you were following me on Twitter this morning — just sayin’.))
If I was writing a book I wouldn’t bother with any other app — heck I’m not writing a book and I still love it.
