Visual Window Snapping

Just got usage permission for the Visual Window Snapping function! It'll be here to stay now.

I'l look into adding:

• Restore Old window Position / Centre window position (depending on which works better)
  - A button in the middle of the pallete

• Move Left a display
  - A button that pops out the left of the widget on mouseover

• Move Right a display
  - A button that pops out to the right of the widget on mouseover

Thanks for the permission!
