It's been almost a week since my last confession, but we've been hard at work. Simon has added a nice little preview to the mini-mode interface, and compiled Tesseract and OCRopus for PPC, so we now have a Universal Binary!
Meanwhile I've been post-processing the text by replacing mis-spelt words. This uses the Mac spellchecker, so it should pick up your custom words. I'm not entirely convinced that it improves overall performance that much, but it does make the output text a lot more plausible.
