Some day. Soon if I can as directions seems to be a very popular feature.
Most likely this will be going in the Enhanced Results or Pro Pack add on. I'm thinking Enhanced Results as I try to more clearly define & segregate what each add-on does...
Enhanced Search = all search UI extensions/mods.
Enhanced Results = search result UI extensions/mods.
Enhanced Maps (coming someday) = all map UI enhancements.
Pro Pack = administration, backend mods (reporting, bulk management, etc.)
Store Pages = the SEO pages for locations.
Tagalong = advanced categorization and taxonomy tools.
Regardless, this is on my short list of patches when I have some time. Hopefully by month-end. Maybe in 3.8 (3.7.8 is already frozen for beta testers).
