We are using a lot of shared reports, and it would be great to see the edit history or at the very least who last modified the report (just like you can see with other contact property changes etc).
I'd like this feature as well. Want to 'lock' certain reports and preferably be able to group them in folders as well. For example I have a biweekly dashboard set, for different teams, and a quarterly etc. Now I have to name them, but since the name is visible in the dashboard itself it has to be very short and preferably nothing.
I agree with all that's being stated. I need to be able to see a detailed history of our reports that show when another user edited them & what info they're adding.
