well, i am making progress on customizing my user profile pages. but one of the things that has been really tough has been the tabbed menu items on the user account pages. they aren’t a part of any menu that can be edited easily – not from Panels or from the Menu admin areas, which are already a little trying as it is. So I started to look to the page.tpl.php file for my theme. Since menu appearance is just that – appearance – they should be handled at the theme level. Here is a stackoverflow article about that concept.
But then I also found this – Tab Tamer! This is a really cool, pretty easy to use module that will allow you to Enable/Disable/Hide any and all tabbed menu items, including the ones on the user account page. Worth checking out.
