While for the first 10 minutes I agreed, I quickly realized that with a day of building familiarity and some brief display customization, productivity is increased. As a hardcore productivity nerd, I first perceived the aesthetic focus as an iOS dumbing-down or cartoonish nonsense getting in the way, but it turns out the thoughtful improvements greatly eclipse the window dressing and I'm seeing improvements in access and organizing speed. To reclaim the old sidebar functionality: Drag your folders to the shortcuts section, and choose the option to display tags in a list in the left hand toolbar, and they will appear as they used to, nested properly ( @apricot13, all my tags beginning w/ "." or "!" are in the proper order, somehow yours must be reversed or buggy). Then the left hand bar will be largely as it used to be, with the bonus of customizable flexibility. All drag and drop functionality into the toolbar is the same, and you now just have extra organizing options. That being said, I noticed some lag/bugs with certain operations, most notably some reduced functionality when editing notes w/ PDFS in the main window, as opposed to popping them out in a single-note window to edit.
