Great multifunctional calculator – Calculator HD++ Review

Got it a few years ago, great app when you need to see individual operations and or advance algebra with functions. You can go back and correct figures, re-calculate or see partial results that you need to add to other figures, for instance very helpful when I am using it to do calculations for budgeting where I have multiple categories with many items in each one of them. The only thing I don’t like very much is that buttons are too small and sometimes it is hard to clear the screen right away. Perhaps one way to improve this is to allow bigger buttons and hold and release keys for additional keys? Pop up adds I know are necessary but it will be nice to be able of choosing between them. Thanks!
