Along with our work on the API, we’re also releasing new features for the web publishing UI.

Re-order elements

You can now switch to the Table of Contents (ToC) of your book while editing, to drag & drop parts/chapters/sections and re-order them the way that you want. Nested ToC re-ordering is supported, which means that you could create a new chapter, move to the ToC and drag & drop several sections into this chapter.

You can also change the type of an element, for example if you don’t need a chapter header anymore, you can turn a chapter into a section.

Sub-sections

Sections can have several levels of sub-sections now. With sections & sub-sections it should be very easy to create any structure that you’d like for your book.
