I would like to be able to view the design of a report in read-only mode without checking it out. Sometimes I want to quickly look at something, and I would like to ensure I don't accidentally change the file contents. I usually remember to discard the changes, but sometimes I check the report back in out of habit. Thanks for your consideration.
In the new Portal that we will be releasing on 8/25 you will be able to click a button to open the report. If no changes are made then you shouldn't need to discard anything when the report is closed.
