That's perfect for me.

I want to create menus and sub menus using paragraph spacing rather than bullets. Likewise, for some of the text blocks I'm using, as well as coloured background tables.

Working with the Styles window docker instead of the ribbon previews, allows a lot more descriptive naming for styles. Spacing can be previewed within the name, as below.

Title
...Menu
......Sub Menu

I'm confident I can create a custom Styles window equally as descriptive as the ribbon preview.

Thanks, it's appreciated.
