The outline numbering dialog [Format->Styles->Catalog->Numbering Styles->Modify]
is a poorly-implemented GUI.  The Position tab has the horizontal spacing
controls out of order: 'Spacing to text'  affects the second line of a
paragraph, and 'Minimum space numbering <-> text' - affects the first line of a
paragraph.  This is counter-intuitive; they should be listed in reverse order,
ie, in the order that the visual representation in that tab suggests - first
line, then second line.

As well, 'Spacing to text' is ambiguous.  what text does this refer to? First
line?  Second line?  Initially it's not clear how 'Spacing to text' is different
to 'Indent', until operating the control shows that it indents all of the
paragraph except for the first line.  So why not call it 'Second line indent'?.
 At least that would suggest its function.

With 'Minimum spacing numbering <-> text', its meaning is reasonably clear, but
its effect is inconsistent.  The term 'Minimum spacing', suggests that the text
will begin at the next tab stop, unless the spacing from the numbering to the
first tab stop is less than the 'Minimum spacing' specified, whereupon the text
will begin after the first tab stop, after inserting that 'Minimum spacing'
between the numbering and the text.  And that's the observed behaviour for
outline numbering at levels two and greater, but for level one, the 'Minimum
spacing' is applied regardless.  There seems to be no way of making level one
text begin at the first tab stop after the numbering.  This results in text in
level one paragraphs being badly aligned with the text of other levels and makes
alignment with these other outline levels impossible.  The behaviour of spacing
after numbering in level one paragraphs should be changed to make it consistent
with the behaviour of levels two and above.  For tidy formatting, my
organisation requires that the start of text in numbered paragraphs lines up
with the numbering of paragraphs in the next level, so this is a showstopper for me.

Although the outline format you've entered is shown in the lower part of the
Position tab and the right side of the Options tab, nothing is shown of this
format in the Outline tab.  Indeed, if you subsequently select one of these
options and click OK, your previously entered settings are lost.  Your only
recourse after a wayward click is to re-enter all your settings.  As well, if
you enter this dialog some time later, there is no way of knowing which of the
examples in the Outline tab hold your settings.  Again, if you click on the
wrong one and click OK, your settings are lost for good.  Expected behaviour for
a useful GUI is for the entered Position and Options settings to be reflected in
the Outline tab, that they be saved for later review, and that the example
modified appear as the selected outline when opening the dialog while the cursor
is in a paragraph holding that numbering style.

So in summary, the outline numbering dialog has sufficient deficiencies in its
user interface functions to warrant improvement.  The 'Spacing to text' term
should be changed to something less confusing, such as 'Second line indent', or
similar.  The order of controls for alignment of the first and subsequent lines
of a paragraph should be swapped to be in a more logical sequence.  The
horizontal spacing following numbering in level one paragraphs should be changed
to match the behaviour of levels two and above.  The Position and Options
settings of the dialog should be reflected in the Outline tab example that was
modified to accept those settings, and all of this should be saved for later
selection and review.  Lastly, the modified example in the Outline tab should be
the default selection when opening this dialog from a paragraph containing this
particular numbering style.
