OK, this works ..., I will translate the english parts in the next days, it seems to be not so much any more, I did already most. Parental Control and the one or other thing ...
BUT I can NOT confirm, that SYM popup does not work, I have my personalized SYM layout with the german Umlaute and my preferred sorting ... as with 3.3
Thanks again!!! A lot of germans will be happy getting the localisation for their K3 in near future.
