For example, for English tools I use Verdana 12pt font size. For user notes I user Verdana 14pt font size. When I click on the smaller A icon in the user notes pane to reduce font size, it reduces Verdana to 11pt equivalent. In English tool pane it takes 3 steps to go down to 11 points. Could you please add those missing steps also to user notes pane?
Here in attachments you can see how both panes look when I reduce font size by one click:
