Is it possible to recover the style of the previous version(V8,V9) in Windows?

Question

In Wolfram Mathematica 10 (Windows paltform),the menu bar and files are combined together.When I narrow the window，it will become ugly shown as below!

So my question is:

Is it possible recover the style of the previous version(V8,V9),

or is it possible to construct a software interface like other software(All files embedded below the menu bar and the main working windows has the normal size like Microsoft Word).

Answer 1

Since in nearly a year nobody has offered a better answer I'll share all I can think to post.

You can remove the menu bar from a window by deleting the "MenuBar" item from the WindowElements Option for the Notebook, which can be done by evaluating:

SetOptions[InputNotebook[], 
  WindowElements -> {"StatusArea", "MemoryMonitor", "MagnificationPopUp", 
   "HorizontalScrollBar", "VerticalScrollBar"}]

That produces a Notebook like this:

The problem is that you lose access to the menu so you would need to restore it before using menu item. You could do that by evaluating:

SetOptions[InputNotebook[], 
  WindowElements -> {"StatusArea", "MemoryMonitor", "MagnificationPopUp", 
   "HorizontalScrollBar", "VerticalScrollBar", "MenuBar"}]

For convenience these two commands could be put in Buttons or a Palette:

Column[{
   Button["Hide Menu Bar", 
    SetOptions[InputNotebook[], 
     WindowElements -> {"StatusArea", "MemoryMonitor", "MagnificationPopUp", 
       "HorizontalScrollBar", "VerticalScrollBar"}]],
   Button["Show Menu Bar", 
    SetOptions[InputNotebook[], 
     WindowElements -> {"StatusArea", "MemoryMonitor", "MagnificationPopUp", 
       "HorizontalScrollBar", "VerticalScrollBar", "MenuBar"}]]
}] // CreatePalette
