Please, can you include all 6 characters layouts options in the properties panel ?

I know. When I wrote you that Faux bold and italic was not displaying either I meant that it would be cool and also logical to see selectable boxes for T T next to theTT TT T¹ T₁ selectable boxes.

Did you perhaps open the context menu for the entire panel (at the top with "Properties: ...") rather than the one in the Text section? The Text and Paragraph sections in the Properties panel each have content menus with options that pertain to those sections. 

I don't use them frequently. I use true bold and italic most of the time.

Actually, I did check Faux Bold and Faux Italic in the context menu and they are not showing up either.
