Abuse of todo lists ultimately leads people to focus on doing even more urgent-but-not-important tasks. To get to important-but-not-urgent, a good task app should have some concept of planning, or identifying action items from first principles. This is inherently a graphical data structure. PERT charts and GANTT charts do this, so does graphviz. Most todo apps do not. Omnifocus does not. Weirdly, most bubble-graph software does not - you can grab a bubble, shake it, and realize it's just a strict hierarchical tree where a bubble can have multiple children, but no bubble has multiple parents. Org-mode kind of has it through tags but I hear it's awkward. taskwarrior does have it, but it's hard to work without creating a bunch of complicated shell aliases (which is doable).
