On my PC, I have the Hide Future Tasks option selected. That's great, as I don't want to see something I don't need to do until next year. However, on my iPhone, those tasks do show up (e.g., on my Hot List). I can't find a setting within the iPhone to hide those tasks.
The Documentation for the iPhone app discusses the "Future Tasks" filter, but when I tap the Filters button at the bottom of the screen, the only two choices are Show Completed and Show Negative Priority. Are the other filters missing or am I missing something?
