Enhancement request for the Count Pages Calibre plugin
I have a suggestion for enhancing the Count Pages Calibre plugin.
When counting the number of pages and words in an ebook, it would be very easy to also calculate how "difficult" it is to read.
Two formulas, Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FK) can be used to measure this. The only thing you need to do to calculate these, except counting the number of words, is counting the number of sentences and syllables in the text. These values could be stored in custom tags.
