Hi Paul,

As the Toolbar markup is provided entirely by the developer in the template, binding any class and styles (or providing them inline like on any other regular DOM element), can be performed without going through the Grid API, e.g.:

https://stackblitz.com/edit/angular-zee1aj?file=app/app.component.ts

This is why we will decline this feature request, as the developers already have full control over the Grid Toolbar styling and content. Let me know if I am missing something, or there is an use case where the approach outlined above is not applicable.
