Having a feature that allows one to reorder the built-in headings, subheadings, paragraph, etc., elements, including user added elements, could help one organize styles in a more efficient manner. For example, if several subtitle elements are created to accompany the use of matching headings: Heading 1 pairs with Subtitle; Heading 2 pairs with user-created Subtitle 2; Heading 3 pairs with Subtitle 3; etc.; this would allow one to quickly scroll through the Styling menu to edit their own 'groupings' of elements.
Furthermore, when one uses the contextual menu and selects the 'T' to apply styling, then the drop-down list of Styles should match how the user has arranged the elements in the Style menu.
It also would be convenient to export the values in a CSV or XLSX file for quicker reference then going back to select each element and try to remember that long-term.
Oh yeah, make the Styling menu's scrollbar function properly with a Wacom tablet, right now those using a Wacom tablet have to use their keyboard's arrows to scroll, not the pen.
