For me, one of the most powerful things about the projection feature is that it forces me to make decisions about which tasks are more important -- if I see at task that hasn't been scheduled I can choose to defer another task or can move that task up the list. It would be really nice to be able to see a list of "tasks that don't fit" at the bottom of the task list -- that I don't have to scroll down to see. That way over the course of the day I can easily see if something important has gotten pushed off of the schedule because of time spent on emergent tasks.
