In the past I have used custom toolbars (lots of them) because then users
could use the tools on the custom toolbars in any workbook they are currently
in.

In XL 2007, as I understand it, one cannot create a new toolbar. What should
I look at to replace this functionality? Add a tab to the Ribbon? If so, will
changes to the Ribbon stay with the application or are they workbook
specific? Are there other options/suggestions?

Thanks much in advance for your assistance/guidance.
