Motivation... For years, PC calculators have been trying to copy handheld calculators in both functionality and appearance. Instead, we should disregard previous conceptions about how a calculator should look and act, and instead consider how a calculator should behave with a full keyboard in mind. The result is simplicity itself, but with many of the advanced features you'd expect from say, a spreadsheet.



Originally, I wanted something like this for myself, but after searching days for a suitable app, nothing turned up. The best I could find was a program called Console Calculator. Having used that for years, it's a decent and solid app surpassing most anything else, but it still suffers from the "command-line" style way of editing when pure text editing would be more flexible.



Finally, I found an application called "Soulver" - an app with the dual-frame design I initially had in mind! The current PC version was too old and had many bugs, but it turned out the Soulver team made great strides in developing a version for the Apple Macintosh. Our hearty congrats go out to Aqualia for creating a wonderful piece of software, but I couldn't wait for a Windows port, hence OpalCalc is the result of many months of dedication.
