In Z-link stats it would be really nice to be able to identify by state, where clicks are coming from. Currently there's only a country-by-country breakdown.

Maybe adding a US state map below the country map?

our currently GeoIP database doesn't provide that level of granularity, so we'd need to source a new one.
