Explainer https://github.com/WICG/manifest-incubations/blob/gh-pages/tabbed-mode-explainer.md Specificationhttps://github.com/WICG/manifest-incubations/pull/95 (draft) Summary Allow web app windows to have a tab strip. This adds a new display mode "tabbed" and a new manifest field to allow customizations to the tab strip. Following a 6-milestone origin trial, we would like to continue experimenting as the feature team is not ready to commit to shipping, and gathered very little data from the initial experiment (as partners we have lined up have not yet started their experiment). Per the Blink policy, we have made substantial progress in these five areas: - Draft spec: https://github.com/WICG/manifest-incubations/pull/95 - TAG review: https://github.com/w3ctag/design-reviews/issues/841 (closed with "unsatisfied"; I have sent a follow-up comment). - Signals requests: - WebKit: https://github.com/WebKit/standards-positions/issues/195 (ignored) - Mozilla: https://github.com/mozilla/standards-positions/issues/811 (closed as not interested in any of "these sorts of features") - Outreach for feedback from spec community: https://developer.chrome.com/docs/capabilities/tabbed-application-mode - WPT tests: https://github.com/web-platform-tests/wpt/blob/master/appmanifest/display-override-member/display-override-member-media-feature-tabbed-manual.tentative.html Blink componentBlink>AppManifest <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EAppManifest> TAG reviewhttps://github.com/w3ctag/design-reviews/issues/841 TAG review statusClosed ("Unsatisfied") Chromium Trial NameWebAppTabStrip Origin trial feedback summary Only a small number of signups, most look like individuals wanting to experiment. A handful of small PWAs are using it. A few large sites signed up for the trial but do not appear to be using it. That said, we think this is a useful feature and want to keep exploring possible customers of the API. I was unable to see any qualitative feedback from registrants. Origin Trial documentation link https://developer.chrome.com/docs/capabilities/tabbed-application-mode Risks Interoperability and Compatibility *Gecko*: Defer (https://github.com/mozilla/standards-positions/issues/811) *WebKit*: No signal ( https://github.com/WebKit/standards-positions/issues/195) *Web developers*: Positive (https://github.com/w3c/manifest/issues/737) *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? N/A Goals for experimentation Roll out one major client and get developer and user feedback. Ongoing technical constraints Reuses browser tab strip code, adding further dependency between the browser tab strip and PWA windows. Debuggability chrome://web-app-internals can be used for debugging, and the new manifest field could also be added to the DevTools Application pane. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?No The origin trial is available on ChromeOS only. Support for other desktop platforms is planned but low priority.
