The one problem I've always found training people how to use MiniPanels is that the local tasks look like a breadcrumb trail. This really needs to be changed. The main Page Manager functionality uses vertical tabs, so changing to that UX would be idea, but almost *anything* else would be better.
Note: This patch requires https://www.drupal.org/node/1300562#comment-6438126 for the divider to work. Otherwise it just moves the links to the right but keeps the "breadcrumb trail" look.
