Hi Edd, I'm glad that you are liking MoI!

re:

Unfortunately, sorry no there isn't any way to modify that particular thing - the viewports are drawn using a separate mechanism from the other parts of the GUI like the toolbars and buttons, the viewports are not controlled by HTML and CSS like those other areas are.

You can change the solid background color of the viewports but there isn't any way to add a gradient effect instead.
