Create esthetic pleasing menu

It would be great if you could make the menu bar (hamburger menu for mobile) to have a small animation when opening and closing. What i mean by that is when you press the hamburger menu icon the lines changes when open and closing the menu. It would also be great to improve the menu itself when it folds out, to be over/on the side of the screen instead of the strange small menu size that opens automatically.
Now you have to change the menu size all the time to lmake it look a little better.

It would look so much better and professional!
