My thinking; at the moment, the filtering functionality is limited by the fact that every filter is "unreviewed + N". There's no way of displaying just reviewed pages (useful if I'm undertaking oversight), or just nominated-for-deletion pages (useful if I'm an admin going through to baleet stuff).
This can be solved by making "unreviewed" a filter, enabled by default but with the option to disable it. It would vastly increase the filtering permutations.
