Why does the new Curvy Shrine website no longer contain a breadcrumbs menu?

For the new version of the Curvy Shrine website I wanted to have a layout with the least amount of clutter. The previous version of curvyshrine.com did not contain a link to the navigation page and topic index pages other than in the breadcrumbs menu, however in the new version of the website both pages are accessible via the buttons top-left (fixed, doesn't move out of view when the page scrolls) and at the bottom of each page, respectively.
