We need /h4, /h5, /h6

In addition to the improved structuring ability - this is important for the ‘collapse content’ feature… If I collapse an h3 block - i may want to have further headings down there and themselves collapsable


This is a blocker for me, as well. Coda’s strength is being able to create structured documents, but it’s really hard to do that with only 3 levels of structure.
