Hi guys;
I'm trying o understand and learn Gantt to implement it in my app. My only reference and doc is the "Project Management" BSV (unless there is some detailed doc somewhere - not the one in User guild) which I'm trying to figure the logic.
So I have a few questions and hope you can help me.
1) When "Editing" a task, there a a button at the top "Add Children" that shows a list of tasks and then at the bottom of the form (Child Tasks section), there is a button "Add Child" that also shows a list of tasks with different order. What are the differences between these two functionalities? What does each one do?

2) To use "Add children", "Add dependencies", "Add child" features, they all show a list of tasks. Does this mean, we have to create a series of "independent" tasks first and then use the "Edit Task" to create relationships between them?
3) Can we provide any way for user to erase or deleted these dependencies and start fresh?
Thank you in advance.
