Sections get an id automatically generated from the title, "journal
entries" and "chart of accounts" are pretty generic concepts, so the
widgets looking for these ids can get enabled on sections they're not
intended to live in.
On the other hand, Sphinx is not likely to generically create classes
for these concepts without being explicitly prompted (via
e.g. rst-class).
In entries explanations and configuration, make it possible to "split"
the list in multiple sub-lists visually: a ``null`` item should just
create an empty space, not display a list item "dot"
* interaction is terrible, select is ugly but radio buttons take way too
much vertical space, no matter whether they're on the left or the
right
* may be possible to unify operations lists between chart of accounts
and entries? Not currently selected set, just the list of possible ops
