One request
Big fan from forever ago. Had free42 on all my PalmOS devices, Android, PC, and i0S since my IPhone 1. However, the current version on iOS has the oldest built-in skins instead of the newest ones. Please fix?

Fantastic!
So nice to have this available. I have always been a diehard HP RPN calculator fan. This app is a faithful and convenient reproduction.
