Numbering of sections/subsections.
Chapter/section/subsection numbering is one of the feature I was looking for, compared to Google Docs. Zoho Docs supports this, but it was very confusing for me that this was under numbered lists. I was looking under View/Edit Document Styles, which IMO would be a more appropriate place to put this, plus give more flexibility, rather than the fixed selection from the numbered lists dropdown.
Also, the ToC is not updated to reflect the selected numbering style - is there a way to accomplish this? Even if I remove the ToC and insert a new one, it still has the "1.a.i" numbering, as before I changed the numbering from the drop-down.
