From the translation I still don't understand your problem, can you attach a screenshot indicating the problem, what app do you use on Win10? what do you use it for?
No, sorry[: I have no idea what you are looking for. I only know how to read AROS EXEC by browser, and at work I expect that will have been Google Chrome. My phone is a dumbphone, so I have very little experience of working with apps.
OK, I am at work, and indeed, it's Google Chrome. It shows an inner box for the translation files, with around it lots of nothing. I was wrong about the exact languages show: It's 3 C-languages and all of Danish. Then it shows the edge of the next column, but we see to little to recognise it as Dutch. The same holds for Edge. The overall character-width is a bit larger, there, but that just means less space is wasted around it.
But, it's a stupid mouse who has only one way out (translating from a Dutch expression): I also have PaleMoon, which is not a work-sanction browser, but I keep it handy as an alternative. That one also is forced to waste lots of space, but for the languages it has a size that fits all languages next to each other.
So, if you need a language to the extreme right, like Finnish, Polish, or Turkisch: PaleMoon is your friend.
