Hello,
Many thanks for including Polish language in the newest version of FiF
I have been testing this Polish language version for some time (7 inch tablet).
I have found some grammatical errors, some editorial and one spelling
I corrected these errors in xml files (corrected files in enclosure).
I hope now it shall be better.
I found out that in Polish version in Preferences->Language, on the list of available languages, there are language names 'Polish' and 'Portuguese' in English instead of Polish (shall be 'Polski' and 'Portugalski'). I prepared two lines of xml to put in the 'array_strings' file to fix this problem. I am not sure if these lines are correct - I developed its using another lines as a pattern. I included these lines in separate file (for safety reasons - I did not want to spoil your work and add potential bug).
Krzysztof
