I can currently fold a function by clicking the [-] at the function declaration (at the top). I would also like to do the same at the function's closing brace (at the bottom). Why do I want this? Sometimes I unfold a longish function, do something near the end and then want to fold it again. It would be nice to fold it at the bottom of the function when that is in view, rather than scrolling up all the way to the top.
