Word counter on homework

This is a tiny thing that I think could be implimented very easily. There is already a counter when you are making the homework, but I would love to have it for when you are grading too. Some homework (granted not a lot) have a requirement of ‘write a minimum of x words’ and for that it could be really nice to have and possibly make some teachers more willing to impliment this as a requirement too if it was easier to check.
