View multiple lines of history setting
Without having to touch again and again, it would be super ideal to view previous lines of calculations, and copy values to present calculations.
I see that users may view previous calculations in history, but there is no option to view a certain number of lines of history WHILE calculating. This function on physical calculators is priceless, and feels limiting to use an advanced iOS without the capability.
Users have the ability to use the tape roll or side by side history in the Landscape mode. Portrait mode history is now under consideration – suggestions welcome!
