Hi WebApps Working Group.

The CSS WG discussed the "pre-LCWD" version of your View Modes Media
Feature spec [1] during our weekly conf call yesterday.
The raw minutes of the call are available [2]. In summary:

1. globally positive feedback about the spec; we agree the feature
    is needed.
2. this should not be restricted to widgets; we suggest to expand
    the scope of the document.
3. about values:
    - is the 'all' value really useful since a (view-mode: all) query
      is always true?
    - a rendering can be 'application' and 'fullscreen'; isn't there
      an orthogonality issue here? Same thing for 'application' and
      'maximized' for instance
    - chrome can be added by the windows manager or by the application
      itself, does it make a difference?
    - is a 'hidden' value needed to query whether a window is visible?
    - if the current medium (CSS-speaking) is 'projection', does it
      assume view-mode is fullscreen? What about the other way round?
      (Opera for instance assumes 'projection' when fullscreen is on)
    - Is it possible to be floating but also have a media type
    - the background of the viewport is often applied through CSS, and
      that could lead to circular dependencies because the media query
      would depend on the result of the cascade
    - more generally, we think some of the value definitions could
      be clearer, it can be hard to understand if a given rendering
      matches a value or not.
4. all these queries could/should have an event-based counterpart so the
    changes are detectable by code. We understand this is outside of the
    scope of this spec but that's still an important comment.
