Just a quick idea I thought of. It would be so much easier to read numbers if commas were added. Like who can quickly figure out how much 14223100 gold would be? Well, unless I'm hard of reading, which is possible too. LOL. 14,223,100 gold would make so much more sense.
Great idea
With the current plan of development of IO I suspect this might be implemented around 2030 after the other so important changes such as naming your provinces
Meanwhile I suggest you buy a calculator
P.S. If you ever do find yourself in possession of 14223100 gold, please pm me, I will help you solve your numerical problem really fast
