I need a program that can be used to create notes and store them as a tree with nodes. What does this mean?
This means that I can write something like this:
Day 1 Task 1 Action 1 Task 2 Action 1 Action 2 Day 2
There will be labels (as shown above) and then a lot of notes attached with the label. The notes shall appear in a separate textbox.
Now I can collapse the entire tree or expand the portions that I need. The data itself could be stored in XML format or JSON or YAML, does not matter.
Does such a program actually exist?
