The current load indicator (the small spinner in the upper left of reports) isn't really sufficient for users. On our larger reports, which can take a while to load, the user sees a large empty area ...
Agreed - this has caused issues with my users on multiple occasions - generally less PBI literate people who cannot see the loading icon and don't realise that their actions are still pending. They often then refresh the page, try again, or do something that makes them frustrated and ditch it.
