Has anyone been able to track down the original author, Eric Le Bail? I wonder if there should be some defined way to fork or reassign plugins which are in danger of becoming “abandonware.”
I hate to thread-drift to a feature request, but where else would I ask:
Would a new version have a find_terms_meta($key, $value) which would more-or-less do a “SELECT meta_id FROM $wptm_table_name WHERE meta_key = %s” (and optionally, “WHERE meta_value” matches $value if given), to permit finding all the categories (or other taxonomies) with a given key? Although come to think of it, that might need some sort of Join to permit searching only certain taxonomies… and it might have to handle the case of a single category having multiple values for a given key. Really it would need to work like get_users(). Hmm…
In any case, that would be very handy for things like populating a drop-down box with all the categories to which we have assigned a certain meta tag.
