I diasagree that you're doing something wrong if you're continually snoozing something. Some jobs need reminders but they don't have to be done immediately. Here's an example of a situation where the current interface is inadequate:

I have a reminder set to buy something on the way somewhere, and one to post a letter. Because I don't know exactly when I'll be passing the place where these need to be done (late train, heavy traffic, etc), these need to be set to the earliest possible time just in case the trip is quick.

Then I'm travelling and I hear the reminders go off, but can't attend to them. Then I get a phone call and have to quickly deal with layers of reminders. (Actually I can answer the call, but can't hang up till the reminders are gone.)

I can't dismiss them - what if I forget them in half an hour when the time is right to do them? I can't open them and reschedule them, it takes so long the caller will have hung up. I can snooze them, but only for 5 minutes (or whatever it's set to), and they're likely to go off again while I'm on the call, and they'll all go off at the same time.

To deal with this situation, I can see these options being useful:
- snooze for various times, say 5, 10, 30, 60 minutes
- snooze till after call
- snooze all (for various times)
- reschedule all (for various times)

The last option would add an increment to the scheduled time rather than snoozing it. One problem with snoozing is that if you accidentally dismiss it later, it can be hard to know what you just dismissed.

All these options would appear below the current list, so they wouldn't bother people who don't work this way.

It would also be nice to be able to call up a list of events that are currently snoozed.
