Orange Dot (Unread Comments) & subtasks

If there's a new comment in a subtask, the orange dot should be shown next to ALL parent tasks as well, so it's easy to find new comments. When you have 2-3 layers of subtasks it's impossible to find all new comments without expanding all the levels.

Maybe it should be a clear dot with orange outline for parent tasks, and the normal filled orange dot for tasks that actually have the unread comment.

I found a filter for Unread tasks, but it should be easier to see right in List View, without having to take extra few steps to use the filters.
