After all the brouhaha about WP getting custom posts types and growing up as a CMS, I see it's still far from having a user friendly interface to actually use this functionality.
1. Where and with what scientific intervention or PHD do I need to create a different archive for different custom post types? Without the use of a plugin please. Is this possible? My custom post types (sadly created using a plugin! -- Custom Post UI -- because WP does not have any human way of creating Custom Post types without tinkering with buggy edits to functions.php) are all there and have "Has Archive" set to TRUE. Now what -- how do I design a template for the archive of this? Especially with custom fields showing in there (beyond title, body, excerpt).
2. Secondly, in the "Single.php" -- can I have "single-cpt1.php", "single-cpt2.php" etc and WP will automatically show the single template based on which custom post it is showing currently?
Would appreciate any real, specific, latest pointers. Google shows me a bunch of different plugins and idiotic blog posts from people tinkering with code in highly inelegant and unsatisfying ways.
