Collection character limits visible

Hi! Just creating my first collection, and it turns out, after I've written title and body text, that there are character limits. Alas, not only are those not visible before you start typing, there is no counter - so I've no idea if I've gone over by 1 character, or 100, unless I use an external app. Any chance of adding in the text to say what the character limits are, and an active counter to let you know when you are approaching that limit?
Thanks!
