Issues regarding Calc: Data > Form... https://help.libreoffice.org/latest/en-US/text/scalc/01/data_form.html?DbPAR=CALC#bm_id240920171018528200 "Data Entry Form is a tool to make table data entry easy in spreadsheets. With the Data Entry Form, you can enter, edit and delete records (or rows) of data and avoid horizontal scrolling when the table has many columns or when some columns are very wide."
The documented behaviour of "new" is, well, weird! Reading the definition of "new" it says "it will jump to the next record". That's not "new", that's "next". It's good that current behaviour is now documented, but it would be nice if it was fixed. There's no point having two buttons, "next" and "new", that both do the same thing ... imnsho, "new" *should* mean "save the current record, and jump to a new record at the end".
Anthony, I don't know what you are talking about. This is no bug report, this is a meta bug to collect bug reports for a single feature in LibreOffice. If you notice an issue please create a new bug report or comment in an existing one.
