This is a feature request to give the post types that this plugin creates proper labels and names. All the post types are called "Post" and all the taxonomy lists are called "Category", both of which are just the WordPress defaults.
The purpose of the request is just to enable site managers to organise the data on their WP site, i.e. being able to see what plugin data belongs to.
The change would be in jobman_page_taxonomy_setup() of functions.php The calls to register_post_type() would need to include 'labels' element, with sub-elements 'name' and 'singular_name'. Similarly for calls to register_taxonomy().
See http://codex.wordpress.org/Function_Reference/register_post_type for more details.
This will not have an operational or functional effect on this plugin, but would help site administrators of complex sites and developers immensely.
