In terms of user interface, I find it a little awkward that "Preferences" calls up a page that reports preferences, but then one still has to click "Edit preferences" to change them. It's very rare that I would seek out the preferences without the intention to make a change. And more than once I've clicked on the settings on that first page in a vain effort to change them as if they were text boxes and not just read-only reports.

Is there any reason why there couldn't simply be the one preferences page, from which one can either see or change the settings?
