I really want that too. I'm using Evernote in my GTD system, so it's becoming vital for me to archive and make invisible some notebooks. The perfect system, as I see it, would be to be able to mark a pile as "invisible" in search, dropdowns, and all notes list. Like a real desk : I have a day to day drawer in which I keep the current notebooks, and another one in which I keep old notebooks. An option on search box would allow to search in invisible items. Same system for EN, just a visibility option for users. I personally (like many other users) don't use tags, so your solution is not viable for me JMichael. What do you think ? I hope Evernote is reading us.
