I have noticed that when you create a report from the Request Report, there is no way to edit the name of the report after you save it.
We also noticed there is no visual indicator showing you that the columns you added/removed or filtering that you changed updated your report either.
If there was a edit menu for the report you create within request reports that allows you to edit the name and columns/filtering options that display "x save report updated" that would be a huge improvement to the system and make the reports in the system much easier and better to use.
