Hi Webkit, I am seeking WebKit's position on the proposal to add an "id" member to the web application manifest(https://www.w3.org/TR/appmanifest/). The proposal explicitly defines what uniquely identifies a web application and allows developers to specify the identifier in the manifest. See spec change pull request https://github.com/w3c/manifest/pull/988 Please let us know if you have any feedback! Thanks, Phillis
