Is there a way to snooze a reminder for a specified period of time?
if you right-click on a task and choose "Reminders", you'll be able to manage every reminder assigned to this task. Unfortunately, there is no option of temporarily disabling it, but you can delete it and then re-add it any time.
We may consider adding such option in the future, though. You're welcome to add a request to our Votebox: http://todoist.com/Vote/
