On this subject, it would be useful to be able to control
title.margin.left for each page-sequence-master; if you have a
relatively large value for it (I use -6pc) title pages that have
centred titles look very odd, as the page "centre" is offset. You can
do customised page masters, of course, but it would be nice not to
have
to for this...
Well, the way the title.left.margin code is written,
everything is indented by that amount *except* items
that explicitly outdent themselves to the left
margin. For example, the header and footer blocks
outdent by the amount of title.left.margin in the
same way the section titles do. That means any
other items like titles that need to be at the
left margin must be outdented to overcome the
page-sequence indent.
The other approach would be to not put the indent on
the page sequence, but to indent all the content that isn't
a section title.
