Comment 22 for bug 748739

The intent here, (of this bug), was to see if there was to be a simple way provided to adjust only the available unity plugin settings and possibly some general settings like desktop size (previously available in gnome-panels workspace switcher.

While post 14 has put a more complete perspective on this, I still believe one should be, unless by release there isn't anything of any significance remaining, at least in regards to user experience.

So in that light the 2 setting's that could be considered a positive for unity and user experience are the launcher mode and launcher/icon size.
If either or both of those remain adjustable then I'm sorry that I can't see the reasoning for not wanting to make this a visible feature of unity.

While obviously ccsm , gconf-editor, ect are available to users, in this limited instance, (unity plugin), they are less than ideal for the general user, many of which will not even know about.
(and there are plugins in ccsm that are quite likely to create issues on their own if enabled and or mis-configured
