I have done this multiple times, and it drives me crazy. I add a new column, and I click in the column heading, thinking I have switched to where I can edit the name. Apparently, I have not switched to edit mode because when I hit the backspace key to delete the default text instead it deletes the column and several others because I hit the backspace key several times. Thank goodness for the undo feature, because I have been able to bring the columns back. It should not be that easy to delete a column. Can you please make it so that hitting the backspace key while in a column heading doesn’t delete columns, or at least make you confirm that you do indeed want to delete the column?
Thanks
