I see this topic was raised many years ago. I use EN for personal, and managing multiple businesses. Plus, others have access to my computer. I encrypt my most personal content but its impractical for entire sets of notes (4k+ and counting). It is also impractical to create multiple accounts because I bounce between all use cases all day long. When can we please have the ability to lock a notebook and all underlying notebooks/notes so I could lock Business 1, Business 2, and Personal. Unlocking each once per day and then knowing that if someone comes to my computer, I can lock down what I need to?
