When you are working in a report, and want to check a previous report for a comment you may have not saved to the template or other reference purpose, you have to exit out of your current report and open the previous report, copy the comment and then go back to the active report and paste.
Since you cant open the software in multiple instances, it would be helpful to have a web page with a list of links for previous reports - so you dont have to go through all the hassle.
