Colapse / expand a Task in task-list : that particular task shall stay at its current screen position, shoudn't move

Hi, Currently : colapse or expand a Task in task-list : the particular task flies up-n-down - I loose my visual focus, need to search for its current position, surprises me, I'm confused... :-/ Shall : the Task shall stay at its current screen position (and I will scroll if I want) - I stay calm, I just continue my work, I'm happy... :-) Cheers, Géza
