Not happy about the latest design. Why has the tree structure Apple mail style been removed in favour of a useless skeumorphic tile/broken list view that jumps around in notebooks. I'm a UI designer myself, and skeumorphic design is important and useful only when it aids in usability - e.g. drop shadows under images to make them look clickable. Skeumorphic images like books etc are a waste of time and only serve to confuse. Why is the only place I can now see my notebook hierarchy is if i press cmd+J ? It feels like a sort of left over feature someone reluctantly left in to appease others in the company who felt that this design might be the wrong approach. I am actively searching for an alternative or for versions of the old app that I can download and use.
