You can now choose which fields (calibre columns) to show and the order in which they appear. To do this, tap on a book to see its details, then tap on the menu button (normally 3 dots) and select "Choose items to display". The "Choose items..." menu line is available only in book details. A dialog will open showing you all the fields in that book. Uncheck the fields you don't want to see, and use the up/down arrows to reorder the fields that you do want to see.
- a long-press on an arrow will move that item 5 rows.
- Scrolling to the bottom of the list will show a Reset button. Tapping this button will restore the list to its default order with all items checked.
- If you change which fields and their order in book details for one book then those settings will be applied in other books.
