The slide choose of secondary functions is so simple, natural and easy that I still can not believe it. Fonts size and buttons are perfect for my age. Brightness of secondary operators are fine. Of course after a while of use I can remember that 'x' variable is over '4' button but still I would like to see it more bright. For my eyes, specially in daylight, secondary functions (except from operators) seems a little too fade.
Thus, I would like to ask, if not too hard, a feature that controls the brightness of these secondary functions, since this is up to personal taste of each user.
Nevertheless, in any case, this calculator seems perfect as it is. Thank you.
This app touches perfection. Congratulations!!
