Comment 3 for bug 248324

I think your second comment is more relevant and a different bug. The casual user also isn't going to know they can add applets, much less having to right-click on the panel and choose "Add to panel". Please create a separate bug on that issue.

A user that is aware what a panel applet is and how to add one may need to unlock the window picker applet anyway in order to have space for new applets, if they are adding more than one.

That being said, I did not realize that ume-config-netbook locked the applets in place. I don't see why we can't leave a bit of space.
