Hi Kendo Team,

It will be a good addition if the ToolBar button controls allow nesting child components or directive to apply custom icon to the buttons. Similar to the button component where it is available as an option.

Currently the developer would need to create a custom control to achieve that withing the ToolBar component:

https://stackblitz.com/edit/angular-qfzm2q-f6fppa?file=src%2Fapp%2Fcustom-tool.component.ts

    <button kendoButton> 
        <fa-icon [icon]="['fab', 'github']"></fa-icon>
        Browse
    </button>

Improving the button controls would allow the developer to directily define the icon inside the ToolBar button control like the following:

    <kendo-toolbar-button>
        <fa-icon icon="calendar" size="lg"></fa-icon>
    </kendo-toolbar-button>

Also this can be concidered for the other component packages that Kendo UI for Angular offers.

Thank you for the concideration.
