Labels for Kerning and OpenType. These labels appear if the design attribute has a non-default value. If you want them to be always visible or hidden, customize labels (see the next feature below).
Customize which labels to show for a whole proof, with the Label Content options in Proof Settings.
Customize the labels for a specific proof section by adding the Header & Labels design attribute.
:fp-layout-waterfall: The Waterfall layout puts font size labels right above each row of text. Previously all font sizes were listed in one label below the header, which was less clear.
