Bolt toolbars are designed to provide a consistent experience in your app. As of Bolt 4.2 we have added more flexibility to what you can show.

Toolbar icons

When in tabs, previously you could add one trailing toolbar icon to toolbars in your app. We have now added the ability to add two. They can be the same, or different, on each tab

When in content we show the option to share and save content from the toolbar. This remains the same, but you have the option to hide those if you don't wish to show either of them.

Toolbar logo

When in tabs you can now choose to display a logo, text or nothing in your toolbar, for every tab type.

When in content the toolbar will always be blank to reserve space for the page title show next to the back arrow.
