Whatever settings I've done, there's one button to make it appear/disappear, and it's very quick. I don't do mine fullscreen though, I prefer just a corner. It stays whatever size I tell it to, I'd assume that can be most of the screen. Also I've turned on "focus mode", which gets rid of the huge titlebar. I use tmux inside of it so I don't need its tab bar or anything either.
