On thing I noticed: in the dialog for editing items, the buttons at the
bottom go [Apply] [Cancel]. Is XFCE going to adopt the ordering system
used in other Gtk+-2.0 apps (including GNOME and ROX), where the 'Yes'
button is always in the bottom-right corner? I think Macs use this style
too.

If you want a nice, well tested options box, you can lift options.c out
of ROX-Filer and drop it in with only minor changes[1]. It's very easy to
use, eg:

	static Option big_icons;

	void module_init(void)
	{
		/* Register options, giving a name and default value */
		option_add_int(&big_icons, "big_icons", TRUE);

		option_add_notify(check_options);
	}

The use it with:

	if (big_icons.int_value == TRUE)
		...
	else
		...

When the user edits the options, check_options is called:

	void check_options(void)
	{
		if (big_icons.has_changed)
			recreate_icons();
	}

The options box is built automatically from an XML file. The 'name'
field corresponds to the name passed to option_add_int().

	<?xml version='1.0' encoding='UTF-8'?>
	<options>
	  <section title='Panel'>
	    <toggle name='big_icons' label='Use large icons'>
	      Turn this option on if you want large icons.
	    </toggle>
	  </section>
	</options>

The options are saved and loaded in an XML format too. You can register
additional widgets (like 'toggle') to extend the basic set (ROX-Filer adds
a 'toolbar' widget to set it toolbar layout, for example).

All changes made in the options box are instant effect, and there is a
Revert button to undo changes. Screenshot here:

[1] Changes needed: create choices_* functions which tell the options
system where to load and save the choices, and remove code for converting
old format options files to XML.
