I've been able to get a custom post type working fine using a example plugin (there are many examples on the web how to do this), and I would like to take advantage of the ease of admin listing tables, adding posts, etc. However, I have a published plugin that uses tabs in the admin section, where each tab typically calls a function which renders the output (one tab for settings, one for rss feeds, etc). I have no idea if it is possible to call the functions that create the tables, etc, for a custom post type. Has anyone seen an example of how this might be done? Thanks.
