Excellent app

EDIT: I knocked off a star because I noticed that even simple calculations are very slow to calculate if done in the advanced menu (about a second of lag). Ideally I'd like calculations done in real time when inputting. Also, no landscape mode. I spent ages looking for a calculator that had the functionality I wanted (e.g. textbook display for input and output) while being easy to use and I found this just as I was about to give up! Some very small things I'd like to see that almost stopped me giving the fifth star before they're implemented, in rough order of importance: The ability to select where I enter characters by tapping at the right point on the expression, not just using the left and right arrows ( maybe add up/down arrows?), calculations not always disappearing when you change mode; mixed fraction output in addition to top-heavy fraction and decimal; maybe multiple variable support in Function; blinking cursor; the Android back button working to get you back out of calculation history, settings and themes; more indication that 2nd and hyp are on; multiplication sign more "lower case" and X variable button being more "upper case".
