The Numbering & Sections Dialogue Panel is long overdue for an upgrade. Page numbering defaults to however the first section is numbered --working with publications, the first section is often Roman numerals while the bulk of the book is Arabic numbering, which means changing the numbering style every time a new section is created.
And the Section Marker field is much too small.
It really would be good if the Section Markers and Text Variables were all combined into a single, flexible method for labeling publication sections.
