Allow showing all tasks, including Peekaboo

I'm using Quire to plan and to monitor my work. I organize my tasks into higher level projects and then actionable subtasks. I track my time on the either the parent task or the subtask, depending on the task.

Sometimes I do some work on a task, record the time, and then decide that I cannot work on the task in the near future, so I peekaboo the parent task. This work great otherwise, but it also hides the task and the time I spent working on it in the Time report view, which I use use to monitor my total working time.

This was highly confusing at the first times, as I was sure I had worked for a whole day on a task before deciding that the task needs to be halted (and hence peekabooed) for some time. Then when I went to see my working time, no time was recorded for that day. Nowadays it still causes annoyance as I need to check my Time report view twice to see everything: Once for All Tasks, and another time for Peekaboo Tasks.

To fix this, I'd like to be able to have a filter which shows both All Tasks and Peekaboo Tasks.
