Calculator Design 04

Hello!
One little point that went nervous for me while using different calculator apps is neccessity to rotate phone. Of course, when you do this you will see all the functions but I don't need them all

So what if I can just swipe a line with not so often used function (such as mc, mr and others) and choose what you need exactly in that moment. I decided to use that idea in my 4th day of DailyUI challenge (sorry for being late)))
