I can never remember whether "Edit Blocking Tasks" means "edit which tasks are blocking this task" or "edit which tasks this task is blocking". Whenever I come to use this, I basically guess the relationship direction, getting it wrong what seems like about 50% of the time. I should be able to remember that "blocking" is the reverse of "blocked", but don't seem to have mastered it so far.

Perhaps I'm a simpleton and it's only me that finds this confusing, but it seems like this could be made clearer by adding a few words of clarification to the Edit Blocking Tasks dialog. "Current blocking tasks" could be changed to "Currently blocking this task", for example.
