Add Data Validation to date fields...
I've mistakenly entered the wrong date format into Kid3 on various occasions and it never validated my input data. Suggestion - either put YYYY-MM-DD grayed out into the background of date fields or do actually validation/restructuring. A lot of US people will by mistake enter MM-DD-YYYY or MM/DD/YYYY which both essentially means bad data is inputted into the ID3 fields.
