One more vote for tabbed notes! I am still using Version 7.14 exclusively because it is simply more efficient. I absolutely love Evernote, it has become a major fixture in both my professional and personal life, and I tell everyone about it. I would love to level up to the latest version and take advantage of new features, but the tab thing is a deal breaker for me. I know it sounds like a petty complaint, but jostling between multiple clients notes without the old tabs just doesn't fit in a 2020 multi-tasking environment. Too many extra steps, Too much waisted screen real estate, too much time and concentration diverted from tasks.
Tabs, and those awesome "prev/next" arrows beneath would make Evernote perfect again!
