RACK42 - A Spreadsheet Application for the DM42

[deetee]

Hi!

I proudly present RACK42 - a small and powerful RPN spreadsheet application for the DM42 hardware.

For more information have a look at https://github.com/zooxo/rack42
or see a short video at https://youtu.be/_lt0Zoqh0og

Thanks in advance for any comment, suggestion or bug to make RACK42 faster, more versatile, stable and intuitive.
Particularly I'm planning to expand the mathematical power of RACK42 (ie conditions, probabilities, hyperbolics, logic, base) and improve the handling (ie copying cell ranges, fixed cell references, more graphic charts) - so I'm curious which features are needed most to build in.

Regards
