Expand/Collapse Subtasks in Tasks Lists
For simplicity and to avoid being overwhelmed with long task lists, it would be great to have a drop down arrow which appears to the left of the task whenever a sub-task is created so that subtasks can be expanded or collapsed at any level to show more or less detail.
This would work in the exact same way as the drop down arrow next to each task list.
This functionality is already there. You can collapse/expand individually lists by clicking on the number of subtasks box next to the parent task title.
Thanks for the suggestion. For now, you can collapse or expand all tasks from the cogwheel menu.
We will consider implementing this for individual tasks if it gets more votes.
