Hi Stuart, I think the problem is not with the used container (GtkBox or GtkGrid), but there is no a simple way to specify border to a container widget or to a custom PushButton and so people who implemented that two buttons were forced to use workarounds (GtkBox in GtkBox) to add the desired white, thin border (actually that is a white background which is partially covered with the inner GtkBox's green background). On the sidebar I don't find any similar custom pushbutton so I don't think it helps.
