The other day I stumbled upon several extensions that I had hoped for but did not know they existed, comparison chart and table creation extensions. These extensions alow your to set up and create grids of information.
I found three options: JE Comparison Charts, Elearning Force Comparison Charts, and Event Table Edit. They all to a pretty good job, none of them cover all the requirements I was hoping for, but could be a huge time saver from many.
