Right, but you could do the same with QOM, it would look like:

GtkDisplay is-a UserInterface (maybe?)
  has-a GtkVirtualConsole "vc0"
  has-a GtkVirtualConsole "vc1"
  ...

GtkVirtualConsole could have a "mode" property.


So from a UI perspective, you would do something like:

-gtk -set /ui/vc0.mode=tab

I think it makes more sense overall as a sub-property of the main ui object 
verses a property of a character device (which is only tangentially related to 
the UI itself).
