Thank you, this solves some problems for me. However now I'm
questioning whether the <LaTeX preamble> section in document->settings
isn't just a shortcut for <AddToPreamble ... EndPreamble> in <local
layout>? In this case I think putting them at the same level is
confusing, and prevented me from ever needing to look deeper in <local
layout>; I understand not all users would want to learn this but it's
three lines to get a LaTeX or HTML preamble. Ideally there would be a
way to keep the generality of the <local layout> section that however
makes it super easy and intuitive to change a preamble.
I leave this decision to you and I'll not file a bug (feature) report
for now, but here's my two cents for keeping things clear and
functional:
1) <LaTeX preamble> section gets removed
2) <local layout> section gets an "advanced" tab with the text entry
we have now, and an "easy" tab made by text boxes, buttons and toggles
(for a start, just containing the infamous LaTeX Preamble and HTML
Preamble, then maybe more).
Except for the advantages in clarity on preambles, I think this would
make way easier not only to tinker with layouts but also to learn how
Lyx works and what are the commands. I know this is a bit of an
overhaul, I'm just leaving this here as an idea.
