The idea simple. Inspired by problems found in Calc type software. As a person who don’t use Calc on a daily basis. I could get some help inspecting a work sheet by initiating an animating so I thought. It would work like a step by step tracer. So that you can see where and how the data are being fetched from and calculated. So if you have a large project with many pages then the visual tracer would jump to the correct table. When doing the tracing. With this I think you could fix errors much more quickly than before.
