Calculator with History

Great calculator, does what I want without a lot of extra clutter. History screen is awesome idea, however I would like to be able to minimize the history screen at times. I would also like to open more then one calculator at a time on my desktop and be able to open and close the history screen and not lose my work. I tried several apps after windows 10 calculator and photo app stopped working and this by far works the best.

I needed to resize this and it doesn't do it very well. And when I try to get it to be smaller, part of the key pad disappears at the bottom. The history tape takes up 3/4ths of the calculator. I can't seem to make it smaller so I can see the part of the number pad at the bottom of the app. I want it narrow so I can see numbers behind it.

Just a real good Calculator. Plain and simple. I really like the running History feature. Very well done.
