Many reasons:
* to allow subtrees to be grafted more easily
* to keep the tags for an entry clean by removing structural tags and
leaving the semantic tags
* to avoid the duplication of expressing the same relationship through
both the tags and list fields
1. Switch from using the text field of lists for storing the associated
filter to using the field `toc-list-filter` (to make it harder to
accidentally parse the text of an ordinary tiddler as a filter)
2. Fix several bugs
The exclude filter `+[tag[intro]]` will produce a document that only
includes the paragraphs with the tag “intro”. These are derived from
the paragraphs in the original document with the CSS class “intro”.
* Add warning in document tiddler toolbar if tiddler already exists
* Live preview document in new window
* Fix slicer.js bug that was preventing the list field of headings from
being filled in correctly
* Rationalise some class names
Now includes a special document view column on the left. Headings can
be expanded/collapsed, and tiddler titles can be inspected and renamed
via the toolbar. Clicking on an entry opens the associated tiddler. The
default tiddler view template includes a special section for tiddlers
that are part of a document
Now we process the rendered HTML of tiddlers, which allows us to
process HTML generated by MS Word. In fact, the HTML that MS Word
generates is so awful, I’ve instead been using Mammoth to do the
conversion: https://github.com/mwilliamson/mammoth.js
Also some necessary improvements to the fake dom implementation.
1. Introduce template tiddlers for the document, each tiddler, and the
tiddler toolbar
2. Move the text slicer toolbar button to the left of the edit button
3. Add a selectable toolbar, currently just containing the tiddler title
