Just tried the new Beta, gave up after a few minutes. On the "old" version I just need 1 (one) click to acess my shortcuts and all other notebooks by that matter. Now I need double or more clicks. Also when I try to switch to anotehr notebook on the top, it just changes the notebook "crumb" but the main note itself I was in, continues to be displayed. Prettier, but with worst usability IMHO.
