How do I know a report is on which object like Task, Project, Proof, Document ?

[#1]

Description - How do I know a report is on which object like Task, Project, Proof, Document. A report doesn't show it either in view mode or in edit mode. In view mode it is showing in bottom right corner only if that report is fetching/showing any records. If no records are there in report then we can't see it. In edit page it is not showing at all which is very inconvenient.

Why is this feature important to you - To know on a report is built on which object 

How would you like the feature to work - Show it somewhere in edit page. Show it on view page other than bottom right corner.

Current Behaviour - In edit page it is not showing at all which is very inconvenient. In view mode it is showing in bottom right corner only if that report is fetching/showing any records.

Currently, one can add a new column to view the report type. The first option in the fields menu is the report type. This is just a workaround, it would be nice to display this directly somewhere.

Yes, we could use an identifier for this especially when working to create multiple reports so to see the object types. It would aid greatly with using text-mode and the API editor.
