As a computer scientist I really love the log2/exp2 key in Tech Calc 64. There are plenty of good calculators but none else provides such a key. I would love to see log2 and exp2 as separate keys, at least in a customizable keyboard. This is just similar to sqr and sqrt, tan and arctan, ln and exp, etc. The font and color scheme in the current version is not optimal for mobile devices. I would prefer light foreground (letter/digit) on darker background for both the keyboard and the display. Many thanks.
