Add an option to not show any words less than X letters

I tend to use this to analyze large paragraphs of data and many times it will pick out things that are not even whole words. e.g. short acronyms or numbered bullets of paragraphs or other things like that.  Since I'm feeding it whole paragraphs, I cannot use a filter for "length."  It'd be good to have an option to not show any words less than X characters.
