All bookmark items are exposed by the Awesome Bar type ahead find feature, but I don't want to see some items. Consider a poorly-maintained bookmark folder that contains bookmarks filed more than 5 years ago. Or, for some people (not for me), bookmarks for "inappropriate" websites. So it would be good to have a new folder option: "Exclude this folder from the search results on location bar." Unfortunately, without such an ability, Awesome Bar is only Annoying Bar for me.
I guess this should go in the awesome bar component, where there are similar requests on file (bug 395161, bug 424557)
Duping to bug 448367 because it is slightly less specific and is similar to some other bugs but still accomplishes this.
