It&#x27;s absolutely horrid. Lets say you want to read everything: first you need to experiment whether depth-first search is going down or right. Then you miss stuff because the down and up buttons on some screens use a lighter shade than what you&#x27;re expecting that is very close to the &quot;nothing here&quot; shade; after figuring this out you go back to examine everything you saw because you might&#x27;ve missed something based on this mysterious hard-to-distinguish shade. Eventually I gave up, maybe he has interesting stuff to say further on but I&#x27;ll never know because I was defeated by terrible UI patterns.<p>Prime example of sacrificing usability for looks.
