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

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);


The use it with:

	if (big_icons.int_value == TRUE)

When the user edits the options, check_options is called:

	void check_options(void)
		if (big_icons.has_changed)

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'?>
	  <section title='Panel'>
	    <toggle name='big_icons' label='Use large icons'>
	      Turn this option on if you want large icons.

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.
