Ability to re-arrange template order in New Blog Templates

At the moment on the template collection page, the templates are displayed by order according to their blog id. This increases my task to test the template layout mood and how they get to displayed on live in Photoshop prior to creating the blog template site. It would be a very much joy if I can drag and drop the order of new blog template sites back-end. Plus the way the templates are called to be displayed on the page with an animation, such as, displayed randomly, in a custom order, or by blog id.
