If you translate the word ‘Search’, then it will not actually show the translated word inside search boxes, and the word ‘search’ that does appear, stops being just grey and disappearing when you click the box, but rather stays in there after you click as searchable text.
Another translation issue is that you used English language files for untranslated languages, in my case “he_IL.po”, which actually contains english text. That would be cool if it was to be used as a base for translations, but the file is not current, it’s missing words from the default “_mantra.po”.
Let me know where you want the Hebrew translation I’m creating posted to.
