Hey @DPI Wizard I really think it would be a good idea if we had a Basic version of the calculator where it didn't have so many different options. I know a lot of people are always asking in the forums what to use but they never have the desire to learn it for their self. Once we figure out the best formula you should make that the only option in the Basic calculator. But then for people who want to mess around with their settings you should have an Advanced calculator.
And one of the new things I really want in the Advanced calculator is the option to set your own monitor distance. ATM they only change in increments of 5% but I'd like to put a decimal number in there instead.
Not sure how much you've got on your plate but I think if you eventually do this it would help your website heaps.
