System preference: AdvancedSearchLanguages The list is built and translated from our database tables. We've been adding missing languages, but I am not sure how to solve this. Could we auto-generate a multi-select pref from the entries in the database? Then you could only see the available options and check/uncheck them. It would also remove the need to figure out the language codes to use.
