I want to throw in another vote for having folders/subfolders. Let me give you a use case that might explain one need: Say the user is using Evernote to track daily tasks. Not as a task list, but a listing of what they've done all day, every day. A running diary of office conversations, work tickets worked on, project tasks worked on, meeting notes, etc. And, say the user is trying to organize these by having a separate notebook for each week. Basically each week's notebook might contain 5+ notes (one for each day). After 20-30 weeks the number of notebooks gets quite long. So, why not have the ability to, say, place each weeks notebook into a folder for that month. Going further, the user might then place those monthly folders into a quarterly folder, with the quarterly folders being placed inside a yearly folder. This keeps the notebook list from getting overly cluttered, and the search function, or tagging, could still be utilized for finding notes on specific things. Scenario B: You are organizing a development project, with a root project folder. You could then have a subfolder for 'requirements' containing notes for focus groups, usability studies, diagrams, etc. You could have a subfolder for code snippets and blog urls relating to the project. You could have a subfolder with notebooks for each QA team member, collecting notes on testing.
