Play area jumps around on screen

[JonSeverinsson]

The two icons on the note toggle button has different sizes, which cases the height off all buttons to change whenever it changes. As the play area is centered on what is left on the screen it will move up or down about a quarter field every time the note toggle button button is pressed, which is verry distracting.

Please consider resizing one of the images to match the size of the other image.
