In the Modern UX Task Timeline view, if you change the order of columns, the task hierarchy/indentation (and the controls to display or hide subtasks) is always kept on the second column.
Steps to Reproduce:
Expected Results: The task hierarchy/indentation is shown only on the Name column
Actual Results: The task hierarchy/indendation is shown on the column which is placed at second position (not on Name)
Any Clarity supported release.
This behavior is working as per the intended design.
The WBS Numbers are fixed and not configurable, the WBS Arrows will always be in the 2nd column because we don't want to lose the ability to see and use the WBS arrows, regardless of the column configured.
For example, if you choose not to use the 'Name' field at all in the configuration and use something else (ID, or some custom field), if we tied it to a specific field like 'Name', then that could be a usability issue. You also have the option to remove all columns in the configuration and you will be left with the WBS numbers and the Gantt chart area.
In the Hierarchy Timeline, there is no WBS Column, so the hierarchical arrows/indentation will always be in the first column regardless of the field selected, for the same reason.
