I'm agree, v10 is so slow and often crashed with an error: "Quit or reopen your Evernote(something like this) - Quit | Reopen", but this buttons doesn't work and a window with an error to appear again and again! Even shortcut for find something in note doesn't work while not set a focus in right note window. After 2 weeks my patience is ended and I switched back to v6.25. It's faster, stable and better than new one.
