Subtask hierarchy not maintained when indenting the parent task
If I take a task with subtasks and move it to be a subtask of another task, the tasks under it maintain their original indent level rather than also indenting one step to the right. This isn't a big deal when there are only a couple of subtasks, but when it's a larger one, it can be pretty time consuming to have to go into each subtask and manually indent each one.
At this point, I'm doing this by moving the task I want to indent under the task that will become the parent, then opening the task and using the arrow key to indent the top-level task. Am I doing something wrong? Is there a better way to do this?
Unfortunately, such option is not available right now and sub-tasks can't move one indent level to the right when you change their parent's indent level.
However, you could change the indent levels of each task much quicker using the drag & drop function. To do so, hover over a task to see the handle icon on the left side of the task, grab it by the icon and while holding it, use the number keys 1, 2, 3 or 4 to set its indent level.
