InfoQube is in the line of ToDoList or viceversa.
I am very fond of ToDoList.
ToDoList have the option to import or export from/to Freemind.
The concept of task list may be reverted into a mind map.
Both programs are superb, but I will stay with TDL
I am searching for a more simple and alternative option to freemind.
I have found Instrumind ThinkComposer
, but seems more complex that freemind. Even with FreePlane I have a mental mess. I am not ready at the moment for big changes. Only use or not Java. And use less memory.
