When I complete a subtask, it won't disappear from the list
When I complete a subtask, it won't disappear from the list. If I want the task to go away, I have to promote it away from it's parent.
Maybe it's supposed to be like this, to keep all parts of a task together. I have larger tasks that are "Priority 1," "Priority 2," etc., so it's a tiny pain.
I'm usually using Todoist in Firefox.
