The Vantage theme itself was released 6 months or so ago, and yes there is certainly even more potential for enhancements to Vantage as future releases are made :)
In response to your specific points:
1. Do you mean specifically the front end design?
2. Yes, we are hoping to have all of our themes responsive by the end of the year.
3. This is something we are already looking at for a future release of the theme.
4. AppThemes doesn't officially support plugins, so integration with this specific plugin isn't necessarily on the cards at this time. This would currently require customization on your part if you were looking to have something like this on your installation of the theme.
5. I believe we are looking into multi-region options, as this is also something people would like to see in the ClassiPress theme. No specific details of when this might be just yet.
6. Yes, events functionality is planned for a future release of Vantage.
7. I'm not aware of plans to integrate our themes together in this manner. Currently, for customers who want to use multiple themes they can install separate instances of WordPress in subdirectories in order to have all of these functions on "one" site. e.g:
yourdomain.com <== Vantage installation
yourdomain.com/classifieds <== ClassiPress installation
yourdomain.com/jobs <== JobRoller installation
With user accounts linked to all installations by way of a
WordPress Multiste setup.
8. 9. & 10. No specific plans at this time, however they are nice ideas and certainly the kind of feature requests we'd be happy to see in the
AppThemes Ideas Exchange. This is where our community can submit and vote for theme ideas and our development team can consider them for future releases. We can't guarantee they would all be implemented, but it gives us an idea of what people want to see in our themes.
Thanks :)
