The editors of the [manifest] spec have now closed all substantive issues for "v1".
The spec defines the following: * A link relationship for manifests (so they can be used with <link rel="manifest">). * A standard file name for a manifest resource ("/.well-known/manifest.json"). Works the same as "/favicon.ico" for when <link rel=manifest> is missing. * The ability to point to a "start-url". * Basic screen orientation hinting for when launching a web app. * Launch the app in different display modes: fullscreen, minimal-ui, open in browser, etc. * A way of for scripts to check if the application was launched from a bookmark (i.e., similar to Safari's navigator.standalone). * requestBookmark(), which is a way for a top-level document to request it be bookmarked by the user. To not piss-off users, requires explicit user action to actually work. Expect <button>install my app</button> everywhere on the Web now :) If you are wondering where some missing feature is, it's probably slated for [v2]. The reason v1 is so small is that it's all we could get agreement on amongst implementers (it's a small set, but it's a good set to kick things off and get us moving... and it's a small spec, so easy to quickly read over). We would appreciate your feedback on this set of features - please file [bugs] on GitHub. We know it doesn't fully realize *the dream* of installable web apps - but it gets us a few steps closer. If we don't get any significant objections, we will request to transition to LC in a week or so.
