In fullscreen mode when the mouse is at the top of the screen and toolbars are visible there three buttons for minimize and exit at the top left. I would like to remove those buttons. There is no option for that available in toolbar customization. Is there some other method of doing that? Those buttons are not at all useful to me in that location and they are a hindrance. I use fullscreen mode much of the time and prefer the 3.x way where I could blindly put the cursor in the top left corner and just click to go back to the previous page. Now I have to avoid accidentally clicking an exit button that really has no business being where it is. It would also be nice if the back button were square instead of round.
