Four things people kept tripping over.
The move controls were a literal ^ and v character. They are arrows now.
Sections can be dragged. The handle is a grip in the block bar, not the block
itself: making the whole container draggable swallows text selection inside its
own textarea, so you could no longer select a word to bold it.
The type palette lived once, at the bottom of the entire guide. Adding a step in
the middle meant adding it at the end and walking it up one press at a time.
There is now an insert point in every gap - and at the end, so there is one way
to add a section rather than two.
Linking to another guide or a KB article meant knowing its slug or id by heart.
A picker searches both by title and writes the markdown link at the cursor. It
offers published guides only - never send a reader to a draft - and it stores an
in-app path rather than an absolute URL, so the link survives the site being
reached by another hostname or mounted under a subpath. The knowledge base is a
separate plugin that a site may not have installed; its absence costs nothing
but its results.
