Idea Summary
The download option in the interactive report is lacking the option to “freeze” the screen while is processing the file, for medium to long running queries I see often requirements to prevent users from clicking elsewhere 

Use Case
Anytime the query behind an interactive report takes more than 10 seconds (with the anxious users of today) there is a need to prevent more actions while they wait for the download
