I use windows 10.. system is in English but I added Polish and Korean in language preferences.. I switch between those quite often.. I noticed that when entering values like "“0.5” from numpad makes problem for ENS when I am in polish mode.. it treats it as comma not as a dot.. I think officially coma separates thousands and millions and dot is proper for fraction part but do You need that in ENS? You could treat both as fractional separation..
OK
I was testing a bit… actually it is the same behavior in sKetchup so maybe ENS inherits it as a plugin.. Maybe some other language users have similar inconvenience or it is only polish keyboard.. (or Windows) Not big thing but it is actually far from numpad to the ‘dot’ key..
