4. custom-look electronic staples and paper clips

1. when stabled or clipped documents are displayed on the desktop, there should be some icon or visual indicator to show the presence of the (possibly removable) staple or paper clip

2. "color=" and "shape=" attributes in the MIME line should allow senders to customize the appearance of individual staples or paper clips.

   • this could have some significance for office filing systems, for instance: a silver paper clip could trigger one workflow component, while a gold paper clip could trigger another.
3. "src=" would allow the specification of a URL of the image to be shown, for even greater control of appearance.
4. it should be possible to specify 3D modelling of your custom paper clip, for electronic desktops being viewed through virtual reality headsets
