{{FeaturePageBody

|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.
