This is very helpful. I would suggest two improvments: 1) If you move a slider bar, it resets the lower-valued slider bars. I don't know if this is intended behavior, but to get to the 8100's, I moved the hundred's bar, then the thousands. But this sequence reset the hundreds to 0, which required me to re-move the hundreds slider bar. 2) Is there a way to have the symbols in each cell as images? Because if I don't have a font install with a particular symbol, those cells display the dreaded empty rectangle.
