Why *must* it be at the top? Other than being an opinion by several
apparently misinformed people, I've seen no evidence or facts to back
up any such claims. As you state it is your opinion/personal taste,
but I don't see how that is what any *users* want or need.

I don't understand this statement. Both suggestions conflict with your
previous statement that it must be at the top. And putting on the right
of the file list makes absolutely no sense. It just makes the dialog
much uglier and much less usable. You'll have either a very large option
menu, or a normally sized option menu with a gigantic area of
whitespace. Neither are desirable and both don't go with what the HIG
says, afaict.

That was one point, yes. I mean, what is the difference between a
thumbnail and a preview? They (are) should be one and the same. In
most cases you are going to get the mime type icon anyway. And no,
in most cases it is not useless. In the cases you are speaking of,
you probably don't have thumbnails for those files, or a way to create
them with current tools. That is not to say that they are useless.
How can you claim something that you have no method of using, is
useless? That makes no sense.

My opinion is that the user shouldn't care what the compression level
is. Disk space is cheap, and most people have enough. The program should
be choosing the most optimal level of compression for the file, without
needing user intervention. Also, most options are per-type, not
per-file, so they would probably be better as extra options in the mime
types system, which any program that supported those mime types, would
read the settings for from there, and save with those options.

It's not clear in anything that there is no way to add extra options.
Opinion or not, applications should not be adding extra widgets to
standard dialogs. If there is any real need for it, there is probably
a much better way of doing it, such is the file type options suggestion
that I provide above.
