And underneath the columns you can have 2 more text boxes that also support HTML tags and [shortcodes]. You can also choose to have just one text area or none. Deleting all text inside the appropriate input in the Parabola Settings will remove this whole text area.
As you can see it's really all up to you. You are free to do whatever you like.
It's a multi-universe of options and you are only limited by your (and our) imagination! Have fun!
