Filter by region
A filter by region (state and cities within that state) such as on http://sydney.gumtree.com.au/
would make ClassiPress much more scalable and interesting to those running a classified site in several cities. I know that the search box can be used to filter but from my experience visitors are not used to this. They rather select a category and then a city (or the other way around) and then expect to have a list of items that can be further filtered (by a price range for example).
Would be awesome if you could implement this in the next release. Thanks heaps...
