I am surprised, since it should work. When you type in a new default
preamble, the preamble of opened documents is not changed, since it
could have been tuned by the user. But if you open a new document
(Command-N), the new default preamble will be used.

Here is a crosspost with toolbox-talk, because there are some
questions for which I would like to get the opinion of as many meople
as possible. But if you think that such cross-post is useless, just
tell me, I'll understand.

For now, I would prefer not to. I prefer to be less precise, but
ensure that the error-line is ok, rather than trying to deduce the
faulty token, with the risk of getting wrong and give a bad
indication. However, since LaTeXiT is open source and will be a
toolbox project, if anybody has the knowledge to improve that, this
will be no problem I think. Do you agree with this opinion ?

This thing is called a "segmented control"; it was already available
with Panther, but with Tiger, it is directly usable from
InterfaceBuilder. At the very beginning of LaTeXiT, I was using radio
buttons, because I did not know the existence of segmented controls.
A friend of mine told me about that, I and find that in this context,
it is much more beautiful.

Here I disagree a little. For people not familiar with LaTeX's
vocabulary, the use of the button becomes obvious. Here again, what
do people think about that ?

A toolbar ? For what purpose ?

Oh, do you mean that the "z" is a mistake (regardless of the fact
that the word does no exist) ? English is not my mother language, so
I did not pay great attention to this. It really does not distrub me
to put an "s" instead.

> [...for the LaTexise] button as well as a button for the drawer, etc.
Do you mean, to open/close the drawers ? Oh, I understand, now :
putting this buttons in the toolbar. Mmmh, it seems to me that my
toolbar would be very "poor" (only two button), so it would not be
very nice.

Haha, you are forgetting french people like me; I do use accentuated
characters, even in an equation label ! And [utf8] does not work,
since the encoding of the input in the textfield is MacOS Roman.

This should be... I will have a look.

You are cheating, using Maarten's pathological latex source ( ;-) no
offense!)
I have an immediate solution, that concerns Herbert's remark too : I
could add a control to add some margin to the default bounding box.
If you need great precision, it would be a textfield. On the
contrary, it would be a slider. But it would need a re-latexisation
(nice word). Any thoughts ?

The preview package seems to give the same results as LaTeXiT:

I do not use the preview package. If you want to get the generated
files, you can look into /private/tmp/folders.[your uid]/Temporary Items
(this is under Tiger the result of NSTemporaryDirectory(). The files
are put there.
