Creating and customizing floating toolbars

How do I create a Floating Toolbar?
Or more accurately, one that I can customize. I can create floating toolbars but can't customize them.
For example, I created a Floating Toolbar (Office) and it includes Expression Web. I don't have that application. How do I delete it from the toolbar?

If I want to create a toolbar from scratch, how do I add my own folders, applications and documents?
I've checked the manual and various Web sites as well as the forum, but found no clear explanation.
Thanks in advance.

Thanks! :smiley:
