You mean there are missing translations? I am surprised as I went to all of the messages in the Excel file (used the mp2xls tool). But I also saw that some buttons still mentioned ‘Create’ rather than ‘Aanmaken’ (nl) in some of the core screens. I was a bit surprised to see that. Did I miss something here?
BTW, thanks for mentioning me in the comments on GitHub but perhaps you would like to change the name into ‘Berend Tel’ (full name) rather than the username.
