A request that's becoming more and more common is for mods to have support for non-English languages. Content Patcher and SMAPI mods both support this, as does Json Assets now. I'd like to see Custom Farming Redux and TMX Loader both support translations, either inline ones like CP/JA or i18n files like SMAPI mods. It also helps prevent crashing issues for mixed CFR/JA packs, where translators try to change the name of the machine and its inputs/products. It will also help reduce the number of duplicate files modders have to maintain for their mods by allowing one download for all languages.
