@ferlanero, I get no clear status of where you are in the processing of the corpus file, since you say you got the hunspell dicts from github. The hunspell dicts cannot be used with OKboard more than as word lists. So please give clear info on if you with "I have already generated the Spanish dictionaries", mean you have copied the hunspell ones only or actually processed a corpus of Spanish texts according to the README.md.
