This comment may dovetail a bit with this one, but simpler.
I’d like to create styles that incorporate more than one attribute. For example an input field may have a stroke and a fill and also additional like corner radius, shadow effects, etc. Currently, each of those attributes (except corner radii which apparently can’t be made into a style) are separate styles. It would be helpful to either create a single style that captures all of those attributes…or maybe (and I’m just spitballing here) the ability to link styles so that one “click” automagically applies multiple styles.
