Hi Joseph,

Thank you for the submitted feature request.

I consulted this request with our developers, and at this stage, there aren't plans to change the UX of the component to all of our libraries.

The developer can add a custom icon and adjust it with some CSS. Afterward, the toggle method can be used to open the popup of the component as demonstrated in the following example:

https://stackblitz.com/edit/angular-4e13r9?file=src%2Fapp%2Fapp.component.ts

Further modifications can be also added like changing the icon depending if the popup is opened or closed.

I hope this helps as it would be the fastest solution for the desired requirement.

Regards,
Yanmario
