HTML5

Modal dialogs

Jochen Eisinger (Chromium) made a proposal for non-modal versions of modal prompts. Basically, when users have to interact with a modal dialog, it blocks the UI for all tabs. People might want to interact with other websites and still not replying right aways to the modal dialog.

Pixel Ratio for canvas

Edward O'Connor (Apple) is asking for a new feature for canvas to store pixel ratio. window.devicePixelRatio expresses the ratio of device pixels to CSS pixels. This new feature would express the ratio of backing store pixels to CSS pixels.

WebApps

Notifications for disconnected Web Apps

Brian Sullivan (ATT) is pushing for adding to the Web stack about for the server to send notifications to the Web apps even when disconnected. In the case Server Sent Events, it is still the client which makes the initial request and there is no way for the server to connect again to the client if the connection has been lost.

Pre-rendering the pages

Gavin Peters is discussing the issues related with the preRendering feature of Chrome browser. There is a timeout of 30s which annoys some sites. It is also not possible for Web sites to get statistics on the benefits (or not) of the feature.

Shadow DOM
