I often have specialist terminology and names in a book which I want to make sure are correct and consistent. Novlr's ability to add these words to a dictionary is almost perfect. Except that the words I define for one book (or series) should be spelling errors or typos in a different book.

I would love to have the ability to have different custom dictionaries for different projects.

I have been searching forever for a writing tool which offers this feature, and so far not found any!
