Thanks. When customizing WPBD I had the following problems in 2.0.5 which required modification to the code rather than just the templates. They are not major, but it looks like I will need to make similar modifications to 2.1.
1. Sticky or featured listings.
These are not rendered using the businessdirectory-listings template so they cannot be customized like the regular listings. I had to modify the sticky_loop function to render these using my own sticky-listings template.
2. Random order listings.
Required changes to wpbusdirman.php to set the orderby to rand. This could also be achieved by adding a random option in the settings.
My theme uses infinite scroll so I had to remove the pagination of the sticky listings in wpbusdirman.php which were rendered using a different query loop.
5. Changing "Listings" to a different term.
I wanted to call my listings something other than "Listings". This required many changes to view.php and wpbusdirman.php. It did not appear to be achievable through changes to the language file.
6. Changes to the templates for adding and managing their listings.
I made changes to various back-end templates like manage-listings in the plug-in /template directory. These templates were not overridden by similar named templates in my theme's /single directory.
7.Customizing my index page.
I used businessdirectory-main-page-categories to customize my main page. Does 2.1 remove this template?
