I love all the different button styles, but note that there is really only one button size - large! Of course I love large buttons, however I come across many situations where I need smaller ones. For example, I am designing a dashboard at the moment that will be built in QlikSense. I want the devs to style it closely to NSW.digital. In terms of size of components, we are at the mercy of what the out of the box sizes are. Compare the button size for filters in the attached image. I am sure many who are building applications will encounter similar scenarios.
