More than one toolbar

Is it possible or will it be possible to add more than one toolbar?
I'd like to write a couple of tool-bar plugins that create separate tool-bars and are attached in different positions (for example one to the top and one to the right)

The issue names no files, tests, or entry points. Begin by inspecting the package's current toolbar and plugin integration, then determine how separate toolbars could be positioned independently; done means multiple plugin-created toolbars can coexist in distinct positions.

Written by the indexing model from the issue text.
