There should be built-in index pages for taxonomies
|Reported by:||frankieroberto||Owned by:|
By default, if you enable 'pretty' permalinks, you get URLs like this for categories and tags: /category/slug, /tag/slug. The same pattern is used when adding custom taxonomy types.
These URLs often suggest to people that it should be possible to go 'up' one level, and access index pages at /category and /tag which list all of the available categories or tags (or maybe just the top x most popular ones for tags).
I'd suggest that we add a new template type of is_archive_index() which uses, in order of preference, taxononmyname-index.php (eg category-index.php), archive-index.php.
Within these templates, the 'loop' should return taxonomy items rather than posts.
This is all possible already using custom templates and get_terms(), but it'd be handy if it was built-in.
