Talking of numbers. If a book has an index, all the page number links are flagged as errors - see attachment. If I ignore all those 'numbers' I get to watch an hourglass for anything up to 10 minutes. Also if a book has a long list of references many of the author names will be flagged as errors.
IMO an index or reference list should be in separate files, and they normally are. So, if one could exclude files from spell checking then one could deal with the index and reference files separately.
Be
nice to have the ability to exclude paragraphs too - to avoid checking quotes in the original vernacular - eg Chaucer, Shakespeare etc
