It would be great if we could select multiple subtasks without being required to be within the master task. There are numerous times I don't see why we wouldn't be able to do this. For example, I might have 8 subtasks due TODAY and I want to change the due date for all of them to TOMORROW. With regular tasks, this is easy. I just click the bubble and make the change. But with subtasks, it doesn't even allow you to select them unless you drill into the master task. In many cases, my master task is nowhere to be found, so it would be a lot easier not to do that.
