This is actually a pretty good calculator. One thing you may want to consider is accommodating people who are color blind. You could perhaps add an option that increases the contrast between different types of buttons.

Thanks! I'll put "optional color contrast increase" on my todo list.

Have a fine weekend,
Acade
