Keep menu always open

[D. C. Stoyanov]

From a request:

I'd love to have the menu always stay open – any ideas?

The purpose of this plugin is to provide a menu whose items are shown or hidden at user discretion rather than offer a static menu. For a menu that always stays open it's better to use plugins that create a list of pages belong to a given namespace. Also notice that since this plugin i) create the menu in the sidebar, which doesn't offer much space in width-wise, and ii) it uses indentation to render nested namespaces, long menus or long names would be printed in a very ugly way.
