If we want to keep the system the way it's structured now, that would be a good way to do it. If we roll with Fear's suggestion though, then none of that becomes necessary (since suggestions would already be classed by the subforum they're in).

The bold prioritisation tags could be somewhat automated if we really want to or we could just manually add the tags easily without any coding. Fear's idea of having a subforum in each section devoted to approved/in-dev suggestions would also work well I think.
