Currently each notification on Android has two buttons: Complete and Postpone.

With the android app notifications, sometimes I find myself accidentally dismissing the notification without realising it, and then having a hard time finding out which task the notification came from. It would be nice to add an option to make the notification non-swipable and then add a button called Dismiss (possibly with a confirmation dialogue) so that I don't accidentally get rid of it.

(This is somewhat of a minor suggestion, because with Notification History enabled I'm able to get the notification back, provided I remember to do so!)
