Perfect / needs longer sounds

Perfect app!!
The best one ever used!!
The only negative point is: too short sounds.....is it possible to have longer notification sounds,more sounds and the possibility,in the settings section,to have notification sounds that never stop till I manually do it in order to be sure Ive read the task?
Thanks a lot for this great app,I hope for new sounds in the future!!
