Today I am looking for a tool capable sorting, filtering and searching the WP content by custom fields.
For example, I’ve succeeded to find a powerful tool for accessing WP content, i.e. WP Smart Sort Premium ([login to view URL]) plugin. Despite some criticism of the plug-in, consider it the most successful tool for sorting, filtering and searching WP content (e.g. see here ([login to view URL])). Unfortunately it happened that in late 2009 [login to view URL] stopped support for plug-in, wiped out it from the site, no contact with the author(s) or successors could be found.
Based on the abovementioned, I have the following request:
• a separate plugin or a theme with built-in widget that have an external interface to sort, filter and search posts/pages by specified custom fields;
• at the same time the following is needed:
o selection of a type of posts’ views:
 full - single post on a page,
 short - muliple posts on a page, each post is restricted to few lines,
 table - one post in one row, fixed columns
 matrix (grid) - several posts in one row;
o pagination of query result a la WP-PageNavi ([login to view URL]) with definition the number of posts per page for each type of view;
o capability to insert a different template for each type of view (to display different set of custom fields);
o ability to disable (through the admin part) output of standard post fields, including: title, date, author.
Eventually the result might have a look like
• [login to view URL]
• [login to view URL]
