The 'Element Options Column' is found on the extreme left side of each record or template form.
If you click anywhere in a row for an element or caption, a big black arrow appears in the element options column for that row
If you right-click on that arrow, a menu will pop-up and offer you options that you will find useful; these options vary depending on the form that you have open at the time
If you click on top box of the element options column (with the horizontal bars), a list of all of the columns that can be displayed in a RIMMF form will display, with a checkbox for each option, allowing you to turn on and off the display of each column
