Calling a Toolbar from within another Toolbar

I would like to have a "toolbar of toolbars." It would be a toolbar with icons in it. Clicking on each icon would bring up a different toolbar.

Maybe this can be done already.

Not sure, but it looks like auto sensing feature (TLB Settings->Auto Sensing). You can switch toolbar content by hot-key or it can be switched depending of active application.

That is not what I want. I want a toolbar that has icons in it. Clicking on an icon brings up another toolbar. Autosensing looks like a completely different thing.
