|Feature overview=When using app tabs, we'd like to encourage hiding the URL and toolbar to leave more space for the web app — but still make it possible to enable them if you want. This setting should be remembered on a per-domain basis.
This feature falls primarily in the '''Experience''' category (from the "Discover, Experience, and Connect" vision statement.)
|Feature requirements=* When making a page into an app tab, the toolbar should disappear.
* It should be possible to right-click the tab and turn the toolbar back on.
