Edit summaries are currently a maximum of 200 characters. It would be useful for editors to be able to see while they are typing in the edit summary a countdown of the remaining characters.
Ideally, any solution to this would not hardcode the character length (because, see Bug 4715 and Bug 4714 - that might change) but base it on the maxlength attribute in the HTML.
