Problem
700 words for the Characters section is not enough. For the sake of proofreading and consistency, I like to keep track of all characters, even minor ones with basic descriptions. And if I want to add more depth to a character profile as I write and develop them, I simply run out of words.

Solution Suggestion
"Characters" with 700 word limit is fine for a kind of index of all the character names.
Create a linked "Profile" sub-section where each character can have up to 1500 words for description.
