Great Add-on. But I only have on problem.
Instead of having space to determine words,
you choose the amount of words.
This isn't a problem when you have shorts words; for, is, at, from. But when you are working with larger words; Stupendous, Generality, Obscenity. It's goes out of my fixation range. So, I was thinking, instead of having the amount of words, you could have the amount of space, pixels, or characters.
