Add options for button placements.

I love the app. But one very minor annoyance I have with it is the layout of the hex digits. I'd like to be able to move them around so that the 0-9 are grouped together like the decimal tab and the A-F are to the left side. Kinda like how it is done on the Windows calculator. I know this is not a trivial addition, but more customization would be a great quality of life improvement.

Hello! Happy to hear that are enjoying the app. Thanks for the suggestion, I agree that it would be a good improvement to add customization of button placements. As you said, it is not a small change, but it's on my list of things to add! I'll update you if I'm able to get this added to the app.
