Does Yojimbo support hierarchical (nested) collections?
Yojimbo does not support hierarchical collections, and we have no current plans to move in this direction, as we think the overall result will be to add clutter and make Yojimbo less approachable and efficient. Instead, we believe that Yojimbo’s tagging support and tag collections offer both a cleaner and a more powerful solution for most purposes. We also plan to add support for user-definable smart collections in a future version, to further extend Yojimbo’s organizational capabilities.
