There are a few things with these custom post types. I asked this at the wrong place as well, but to also get the attention of people who are not interested in that plugin, another thread here.
My current custom post type situation is as follows: with the use of a plugin I created custom post types. Then I manually created new templates to display these custom post types and I created pages with these templates, because the plugin seems to not offer 'indexes' for the custom post types. This works fine enough for now. Now I for example have a custom post type "quotes" which displays at gangleri.nl/bookreviews/quotes, but when I tag a post with for example "dumezil" to group all the quotes of Georges Dumézil, this tag has the slug gangleri.nl/bookreviews/dumezil, while it should be gangleri.nl/bookreviews/quotes/dumezil.
Did I miss something or has something been missed?
Then there are some other things. The default single.php is used, the same sidebars as elsewhere, it is unclear if WP sees the posts there as posts or a page (since I use a page to display it), but I think the first, 'recent posts' will require some coding. That sort of things. All in development? But it seems plugins are released rapidly.
There is a plugin that says to fill some of these holes, but it doesn't work, maybe because I already have another custom post type plugin installed and it does not seem to solve my most pressing problem of tagging. Any suggestions?
