I'm working on adding the

I'm working on adding the sigma operator, in the standard n=1..x configuration. Arrays might be a bit trickier, but they could fit in with some planned matrix math features.

Storing answer values has made sense on calculators or applications like Mathematica that operate on one line after the next of calculations. With the focus of Pi Cubed being around one equation or calculation at a time, I'm not sure that it fits as well here. However, I might extend the copy-and-paste functionality I'm adding so that you could copy the answer value and paste it in the next calculation you perform.

As far as features go, I just prioritize the ones I know of, take care of the easy ones first, then work my way down that list. I've been a little distracted with the iPhone 3.0 update and all the new stuff at WWDC, but I should be able to get a couple of updates out here in short order.
