For viewing past reports: there is now the option to see all recently run reports if you select the “All Reports” option at the top of the left-hand nav. You can filter the table via the search bar to find various report types or you can use the column headers to sort.
That’s great, but it doesn’t help. I can’t explain it without showing you and this public forum is not a good place for me to post screenshots of my reports/structure.
You have the report tree. Why not just put each instance of the history under its report under the tree? Just make each instance of the report a child on the tree and when i click on it i get an info tab where i can manage the instance and a preview tab where i can get a preview of the data? HTML/PDF would be easy. CSV would be almost as easy.
This would also make it clearer when clicking the play button what is actually happening. The play button doesn’t rerun a specific instance of the report (which is the indication it currently gives), but runs the parent report, generating a new instance of the report data.
