Update your status show characters left when typing in the text field, would be nice to have this while typing in the new thread/new post text field. To know when you reach the 10,000 chars limit. Usefull when posting long articles etc.
(Stupid me, I wrote a reply then closed the window instead of hitting post)
It's hard to do this in the WYSIWYG editor because the HTML has to be converted to BB code and that will create a sizable different in text length. (The BB code counts in that length; this is very much intentional.) In the non-WYSIWYG editor, there are conversions as well, though not particularly significant.
