Not a fan of hamburger menu but I disagree this is an improvement, the scrollbar wasn't visible on my platform (chrome, mac) and it wasn't clear how to scroll.

Not a fan of hamburger menu but I disagree this is an improvement, the scrollbar wasn't visible on my platform (chrome, mac) and it wasn't clear how to scroll. I'm not even sure how I would horizontally scroll with a mouse (I seem to remember something about hold middle clicking and dragging). Why not just have all the links in multiple rows or have a few subcategories + expand and navigate through the list of links?
