As a Product Manager, I would like to filter reports by Last Modified so that it's easier to find reports. I can already filter using Created By, Shared With, and Report Type, and a number of other ways but modified date is not one of them. Stretch goal: Let me choose from a list of attributes by which to filter -- much like we can do in other areas.
Thank you for your idea. One available solution that may help in this case is to switch to a list view of reports (see the icons in the screenshot for details) and then sort the report by the Date modified column.
Given the availability of this option and current priorities, we are unlikely to implement this request at this time.
