I love using Astrid for organizing my tasks and reminding me of when things should be getting done. I really need an organizer that can remind me when to get things done. So when my volume is up on my phone it plays the notification sound - but is there a way to have it vibrate on notifications when my phone is set to vibrate mode???? I can't figure this out - and it is very important during work hours to be reminded of these things.... any help??
