SUGGESTION: "Display Options" for Vector layers

Last build (26July)
Win7 Ultimate SP1

I am not much of vector layers but…

The Display Option panel (on the right) has two options for working exclusively on vector layers, the “show invisible lines” and the “show outlines only” ´s options.
Suggestion: to make customizable shortcuts on the Preferences Panel for both options.

NOTE: not sure if both options are the very same as the ones presented on the Options panel (on the left) in which we can see “Contours” (= show invisible lines?) and “Invisible” (= show outlines only?)
