Hi Evan, the themes are designed for specific purposes (ClassiPress for classified ads and Vantage for directory listings), so whilst yes you can modify either of these themes to suit your needs, Vantage itself is going to continue to be developed towards the directory listings purpose, and thus offer more features that ClassiPress will not. The next major release of
Vantage v1.2 will include:
Events
Sortable listings pages
Multiple listings on a single map
Large map for home page and listings pages
Different map pins for events and listings
Draggable map pins when creating a listing
Driving instructions
Contact business owner forms
Rich snippet microdata for
SEO
New pricing plans that allow multiple categories
There are no immediate plans at this time for ClassiPress to include multiple category selection for users (although you can manually do this from the
wp-admin), so Vantage will indeed have this functionality first. Thanks.
