Evernote staff: this MacOS release is reckless. Long time user here too. How on earth can your quality process involve releasing into production what's effectively a beta where crucial--even basic--aspects are missing? Tabs taken away? Layout and style options missing? 'Recent notes' forced back into the sidebar without ability to remove them. And...quick-note functionality held hostage by a combination of poor design philosophy, feature vision/execution, and development capability?!
This reminds me of too many prior upgrades when I joined the first wave of fools only to get burned in return for my dollars and eagerness to demonstrate loyalty through early adoption. Well congratulations, you got me again. Do not underestimate the seriousness of undermining loyalty and quality of experience (and therefore value) by willfully removing key features. If you insist on doing this moving forward--and I have every confidence that you do--please seriously consider adding to the start of all new version installs (I refuse to call them upgrades at this point) a very obvious warning about what key features will be lost or altered, even if it's for an interim period in the roadmap.
Any time customers, especially paying customers, even create the idea to revert to a prior version, you've screwed up. Sometime around 2014-15 Firefox became such a flaming heap of trash with poor usability that it easily drove me to Chrome as the predominant option for good. This is analogous. Hooray for the improved backend but don't get it twisted: clear function first, looks second.
