Simon and group,
I am working on  a new SC about showing/hiding toolbars. When I
started on it this morning, I thought of rewriting the current 2.8.1
to include the showing/hiding of the actual toolbar in addition to the
individual controls. This would also give the user the ability (that
does not yet exist) to rearrange the display order of the toolbars.
Currently, you can show/hide toolbars but only in the order in which
the toolbars were installed.

What are your thoughts about extending 2.8.1 to include whole toolbars
in addition to components within toolbars?

I will continue working on the IER and new SC, in the interim.
