I took some time to return to town, but I sent you the translation files :).
Yes those should also be translated, if you open any text inside the scenes you will see lines formatted as ‘text = “…”’ or ‘label = “…”’, so you just need to translate the contents of “…” and leave the text/label keywords as they are :).
Then on the file “es.po” you just need to translate the contents of ‘msgstr “…”’ and leave all ‘msgid “…”’ as they are.
