I would like to find a way to structure my notes similar to what D-Nick is trying for. And what DTLow suggests, but without having to use Tags.
For example, in my traditional paper-based office I have a filing cabinet drawer for Workshops. Within that drawer I have file folders for individual workshops. Within each file folder I have multiple pieces of paper that are the equivalent of notes (lists, maps, research material, etc.)
Using Evernote, I want to be able to click on Workshops in the Notebooks section of the sidebar, then click on a workshop name to see all the notes that pertain to that workshop.
Is there a way to structure Evernote like this? I really don't want to have to tag everything and then search on tags.
