1. CSS font-stretch

    If a font has multiple types of variations based on the width of characters, this property allows the appropriate one to be selected. The property in itself does not cause the browser to stretch to a font. Note that `font-stretch` is an alias of the [`font-width`](/wf-font-width) CSS property.

  2. Customizable Select element

    Proposal for a customizable `<select>` element. Previously envisioned as a separate element (`<selectlist>` or `<selectmenu>`).
