You can't expand out a group in the Layer List sidebar, however you can do so in the Outline Editor, provided all you need do is change the label of the component of the group.

If you need to change the style or size of a group's individual components without ungrouping, you can click on the group and click a second time on the object you want to edit to sub-select it, make your changes, and then move on.

Agreed that we should allow sun-selection like this from the List view as well as the Outline Editor, hopefully we can implement that in the future.
