I’m still playing around with the baseblog theme.
It has article.text.php, article.link.php and article.video.php in the template folder. I’ve added an article.test.php and changed its title within.
But I cannot select this new template when adding a new blog entry in the panel. Only the three aforementioned templates can be selected.
When I’m adding a new typo entry (another top level folder), I see my new article.test.php, as well as Search and Feed.
Where is that restriction set? I don’t see anything in the text files of the folders, I don’t see anything in the blueprints, and the documentation may say something about it, but not in a form that I can recognize as pertinent to this question.
