I think Preferences (both old and new) have a problem. The name clashing you see is a symptom of the problem. But the problem is having all packages use the central Preferences mechanism. Your proposal makes me remember the Windows Registry: A central repository of preferences/options/configurations for all apps in the system. It also has a hierarchical structure to support multiple users. Some of the problems of this approach (in particular in Windows) are: - Modifying anything there is very dangerous. A single mistake could break the whole system beyond repair. So, everybody is really afraid of touching it. - Anyone could modify stuff that isn't their business at all - When you remove an app, in many cases they leave garbage there - Sometimes you completely uninstall an app to solve some problem, and you reinstall it afterwards. The problem is never solved because it was garbage left in the Registry and never cleaned. Only solution is to format disk and reinstall Windows (and losing everything else, of course) I think it would be much better, as Luciano also suggests, to use the central Preference registry only for the base image, and have a good way to let packages have their own.

To access a preference in non base image category I propose the message #at:in: #at:in:put, #instanceAt:in: PreferenceNG at: #textSize in: #zork PreferenceNG at: #textSize in: #zork put: 12 (the instantiate method can still be used to edit a preference value: PreferenceNG name: #textSize category: #zork value: 12) Then I propose shortcuts compatible with the existing protocol: Preference at: #zork:textSize Preference at: #zork:textSize put: 16 Preference instanceAt: #zork:textSize I will have to write a method to move the preferences in their own category dictionaries.
