Comment 4 for bug 489528

I have attached a patch which contains some of my ideas.

First of all I have removed all the button from the left and made them into a toolbar. The checkitem (replace document) has also been removed. I think when a user selects 'scan' a dialog should appear asking if they want to overwrite or not. A view menu has also been added to control the toolbar's visibility

I have added the zoom icons to the zoom slider and added the continuous scan menuitem.

Finally I have put the image preview in a frame to make it have a border.

Some of these changes need the C code to go with it, however since I am a python programmer, I shall leave that to you Robert :-)
