I just discovered that WordPress.com supports custom menus. It’s now possible to mix pages with blog categories in your menu structure (although not all themes support this yet).
Have you ever wanted to have a different title for one of your pages than the label displayed in your site’s navigation? Ever wanted to change the order of the list of pages to an order you chose yourself? Ever wanted to be able to mix pages, categories, and random links in your navigation instead of your theme deciding for you?
Jane Wells, New Custom Menus Feature (and a few others)
This is a great new feature and one I’m looking forward to using in the future.
Update: Find the themes that support Custom Menus in WordPress.com by using the Custom Menu Feature Filter.
