Revision as of 21:37, 15 July 2013

There are features that have been requested, but for which we are lacking implementor interest. Without two or more vendors interested in implementing the feature, they are unlikely to get added to the specs.

Feature Interest indicated by... Comments
Mozilla (Firefox) Opera Microsoft (IE) Apple (Safari) Google (Chrome) Others
Cross-origin seamless iframes Boris Zbarsky Adam Barth Pending input on this thread
HTMLCanvasElement.printCallback API Julian Viereck
Metadata API for media elements Ralph Giles Also needs a spec for the metadata schema
Adding defer/async to inline scripts Jonas Sicking
<meta name="referrer"> Adam Barth
Location.ancestorOrigins Already implemented Negative feedback from Tobie Langel
A method to trigger autofill Elliott Sprehn, Peter Kasting
Prerendering APIs Gavin Peters Needs detailed specification work to describe what happens with scripts running in the prerender context (since normally scripts can't run in non-active documents, and normally there's only one active document per session history).
APIs for 'palpable' content (at the bottom) Ojan Vofai
Some way to add files to <input type=file> Jonas Sicking Nico Weber
Appcache: More detail in error events Michael Nordman
Making drawImage() have a mode to clamp at source rectangle Justin Novosad

Canvas: Stroke alignment
Canvas: Page flipping for the 2D context James Robinson
Canvas: control over when shadows paint
<img srcset>: a mechanism to enable adaptive images
locale=""
<video> currentTime and seek using rational numbers Jer Noble Would expose the video's timebase, too, assuming it's constant. See also next line.
video source material metrics (e.g. frame rate for fixed-frame-rate video data)
Exception object as fifth argument to onerror zcorpan?
Cross-origin workers Travis Leithead? Ojan Vafai
Deferring <img> loads until the image is needed
API to request Web Worker latency guarantees (in exchange for guaranteeing low CPU usage)
SearchBox API Tony Gentilcore
