Is there an application that combines MindMap and a structured notebook?

Question

Task Management

I would like to have a tree-like binding of either plain text or tasks directly to MindMap (link diagram).
Possibly with links to other diagrams.
Interested in a free version of the application or one that can be found with a tablet.
Prompt, advise, share. Very interesting.

Answer 1

I recommend mindmeister.net where you can attach notes and links to elements.
