The most unique thing about the product is not being locked into a set hierarchy. Circles do not seem to contain child circles - they merely reference them This is great because you can replicate tags, folders or any other organization structure this way Other project management tools enforce a rigid containment hierarchy (projects contain tasks which contain subtasks) and allow flexible organization only through filters (which tend to produce flat and not tree-like output). Wormhole would let me create hierarchical views without copying content
