WBS with Gantt Calendar

We can create Gantt chart with actual date, but cannot create planning with WBS, such as with duration for each task but no planned date.

So it’ll be verify nice if we could create WBS.

As WBS, there should be the following features:

• Tasks, sub-tasks for tasks/sub-tasks

  • Assignee

  • Task dependencies, like “blocked by” or “is blocking” and postpone it until blocking task would be done.

• Duration for each leaf-task, but not for parent task, for parent task, it should be calculated by sub-tasks, but not add all of them because some tasks might be done in parallel.

• Work calendars, to exclude national holidays and annual leaves.

With these features, I’d like to see Gantt Chart / Calendar View when I set the date for the first task, in planning phase, it’s nice to be “Day 1”, not actual date.
