Hi, this is a minor UI change but i think it would be greatly helpful and a time saver
When adding a new subtask to a primary task that already has tasks. e.g. adding a new subtask to WBS 1.4 (where 1.4.1.1 and 1.4.1.2 already exist). GANTT creates a new task at 1.4.1.1 and pushes what was previously 1.4.1.1 down to 1.4.1.2 (and 1.4.1.2 down to 1.4.1.3)
That's kind of backwards and now forces me to manually drag the newly created subtask at the end of the subtask list. I don't think I know anyone that adds subtasks to a project from last to first.
Ideally the new subtask should be created at 1.4.1.3 and new subtasks should be created at the end of the current subtask list.
