When I change anything about a task I would expect the modification date to change, but it seems that when I just change the title of a task (at least on my iPod Touch), then the mod date is not changed.
In this case, it's not even a question of not displaying the date correctly, since the task stays where it is when the tasks are sorted by mod date.
So, is this a bug, or is it supposed to be like this? And if it's supposed to be like this, what's the logic? Thanks!
