Right click on the list header to choose which idea attributes to display : in the popup menu, select the "Columns" item, then click on every idea attribute you want to display or hide. A final click outside the menu validates your choices.

You can also resize each column width, change column display order by dragging / dropping their headers, and resize the whole dialog : the global configuration of this grid report will be recalled later (unless when the "Cancel" button is pressed).
