My todos tend to have lots of dependencies, and a graph (i.e. nodes and edges, or vertices and arcs if you prefer) is a much more expressive representation for this kind of structure. Somehow, though, I can't find any existing website or software that does this...

I used to just manage this on paper, but now I'm working with several other people and it'd be great to have some way to collaboratively work with something like this.

Do you mean like a gannt chart or something? I've seen a few apps that have gannt chart abilities, but not sure what you mean exactly. Can you explain a bit more? – Task Management - Jul 11 '14 at 21:47 looks like what you are looking for.

Subtask too.

Basically I googled "mindmap task management", you may find more alternatives in the results.

Do you have any personal experiences with these tools? – Johan Karlsson Jul 16 '14 at 9:27
This looks so simple and beautiful I am tempted to get the $15/mo subscription. – Gaʀʀʏ Jul 25 '14 at 15:00 may be a fit for you. It's basically an outline editor with cross-node search, and you can annotate anything with labels. Labels can be used to filter and connect nodes.

Check out their usage videos for a quick demonstration.

You can take the free version very far, and (if I recall correctly) this includes basic sharing and collaboration.

I've developed with this scenario in mind. I too saw the need to express dependencies and found that existing applications did not adequately capture this even through sub tasking. Planzu has a brainstorm and outline feature that let's you build chains of dependencies in an outline structure. Each of these items can then be assigned to contexts, a calendar, etc. It seeks to find the balance between maintaining separate lists and yet also being able to link ideas together into plans of action.

The app is in its infancy and there is plenty more to be added but the core fundamental features are in place and usable. Feel free to try it out.
