Either to read its selected state, or to receive an on() event when a style is selected/deselected. I want my plugin to be able to link with existing styles, but to pick them I either have to go the pick object route (which won’t let me pick styles that aren’t assigned to anything), or recreate a style list inside my plugin, which seems wasteful.
Not possible but would definitely be useful. Feel free to move this to #plugin-widget-api:feedback category
