Remember user preferences
During UI review, Cathy changed various lists to show 30 items rather then the default of 10. This information is forgotten as soon as you navigate away from the page. This information should be persistent to some degree. Maybe stored in cookies?
Over time, there will be a lot more personal preferences that we should keep somehow. So the solution should be more flexible than just this example.
For background, see #278 (closed), second to last item.
