EXCELLENT calculator, constructive feedback below

I was looking for an HP32 equivalent, but found that allRPNCalc was better than the real HP calc (except no programmability). The keys are good size, the response is fast, trig accuracy seems good (tan(pi)), register display is nice extra not found on real calc, and on-line update of currency conversion rates are unique to networked calculator. However, some of the currency conversions are inverted wrt arrow keys, e.g. Japanese Yen or Swiss Franc to US dollar. Some of the common conversion rates used for news are opposites, and maybe the online feature used here is not taking that into account. Please fix this. Also, dedicated x^3 and cube-root-x is not necessary given y^x and xth-root-y. 2 limited programmable keys would have been nice. I always use dBs, so 10*log10(x) and 10^(x/10) would have been my choice there. Thanks for a great app.
