When creating a serial prediction pattern, one mandatory field is called "First issue publication date"- this title could be misleading to users of Koha thinking that date needs to be the first-ever publication date versus the first publication date of the serial that is being added to Koha. The manual describes this field as: In ‘First issue publication date’ you want to enter the date of the issue you have in your hand, the date from which the prediction pattern will start. It would be nice to add a helper tool here with maybe a question mark (like Koha does in the Messaging Preferences by Digest) to let the user know what is really needed here. Another option would be to change the language for this field completely. Either way would be good!
