Building a die roller

[Mercule]

Okay, I'm looking for an easy project to do on my iPAQ, just to play around. I've decided that a die roller would be a great thing to have handy, but the few that I've downloaded always fall flat and dice are easier/faster to use. Which brings me to my reason for posting:

What features would make a die roller for a handheld attractive?

The simplest form would be a picklist for number of dice, a picklist for die type, and a place to enter an addend and a multiplier, but that seems that it'd be a bit too slow. So, I was thinking of adding a way to name and save die roll formulas. Does that sound like a good plan? Anything else that'd be nice to see?

Thanks for any help/opinions. When I get it done, I'll make the app (and source code, if someone points me to an appropriate site) available for anyone who wants it.

The PPC dice roller that I wrote (that I quite liked, but that was lost in a disk drive failure) featured a graphic of each die type that you could tap for an instant result, a quick way to have multiple dice and add modifiers, and the ability to save (and optionally name) dice combinations and modifiers. It also kept a running record of all rolls so you could go back and look at what you had rolled. The dice graphics (each of which was a different color) were there to make an instant roll as easy as real dice.

I have no time to re-write it, unfortunately, but that's the kind of thing I'd like to see.
