LYR-9: Layer > Layer Styles > Layer Style Options... (layer.style.options) and choosing a style from that menu open a Layer Style dialog: style list with check boxes (Blending Options first) and the selected style's controls built from its layerStyles properties, edited live through prop.set (one undo step per control); Cancel rolls back everything done since it opened.
