I’ll add both, ipynb and Ruby to the list!
Thank you so much for this suggestion too! I’ll definitely check out One Dark Pro!
For your weird request — it’s definitely something that I’ve been thinking about too, but color mixing took tons of studying over the years and takes hours (even days) to perfect it, so I will have to make it a premium product. I have bills to pay and surgery to save up for too, so the only way I could make this possible is by monetizing it. I am still unsure about how much it would cost, but I hope you understand why!!
