Tabs are a MUST! I think it's a very common thing to be working in multiple notes at once, and it's sloppy sloppy sloppy to do it with a whole bunch of windows open. I love the updated app, but taking out tabs was a huge mistake. For me it completely invalidates the value of the update because my overall functionality is badly impaired. Super sad to have to revert to the legacy version when you all worked so hard on this update!
