Problem Statement

1. Inputs in scientific mode cannot be modified at exact position after typed in, as people who use this mode are expecting some more control over the equation, that feature is a must from my perspective.
2. Button's function is illogical. When I click log, this will act as a postfix notation; however, if I click power, it will act as an infix notation. Why?
