|Feature open issues and risks=* Dao has suggested that we implement a separate URL entry widget instead of showing the toolbar.
|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.
|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.
** This setting should be remembered on a per-domain basis.
* When using keyboard shortcuts to get to URL field or search field, it should be turned on for the duration of the interaction, then disappear again.
|Feature ux design=Interaction is described in {{bug|644721}}.
