I'm a former Premium power user and evangelist with over 1,000 notes. I used Evernote on iPhone, iPad, Windows, Mac, Web and Apple Watch. I was happy with my yearly premium subscription. I love how you guys are constantly improving the app (templates, dark mode, etc) and listening to user feedback, so I'm hoping you will listen to mine. Alas, I had to give up Evernote, because of a single, huge problem. There is no real 3-level hierarchy. I tried using stacks, but their only purpose is to make the notebook list more organized, nothing more. Because there is no real 3rd level above notebooks, (or one between notebooks and notes), I cannot have two notebooks with the same name.Example: I work with 15 clients, so I have a notebook for each one. If I want to have further subdivisions, let's say for each client I want to divide my notes between "Marketing" and "Operations", my only option is to go with Stacks. But if I try to create a notebook named Marketing for each client/stack, Evernote will rename it to Marketing 1, Marketing 2, etc. This is because Stacks are not a true categorization label. So right now my only option would be to create notebooks named "Client 1 Marketing", "Client 2 Operations" and so on. Only I don't have 2 categories for each big notebook, I have more like 10-15. I'm sure there's a reason why you're not doing the whole 3-level thing. Probably user-friendliness. And as a Product Manager, I agree with simplicity. But please, give me a switch somewhere deep in the settings to enable this feature. Meanwhile, I'll be on Onenote.
