Hi, and thaks for this killer app!
I have a request for a feature that I consider very useful: to detect repetitions of words in proximity, I use a software called Repetition Detector. What it does is analyze a text and point out which words are used in close proximity to each other; as you would agree, it is not the same to repeat a word 20 times in a long text as it is to repeat it 20 times in a single page (or paragrahp!).
Thanks for your time!
