I'm currently writing the "Welcome" page for my modpack in English, but I know lots of people who play the pack in a different language and would love to read a translated version. Currently, at least to me there's no way to add for example a Spanish, German or French version of the welcome text that then gets replaced based on the selected language. I bet it's not too complex to add, is it? Just add a folder structure - by default and drop a .txt file for each language - by the modpack dev. It would make it even more useful in the near future.
I'd benefit from a 1.18.2 version of said feature.
Thanks for reading!
