As a user I would like visual feedback when executing queries so that I can tell that the operation was sent to the server and is currently in progress (remove uncertainty).

From Joe:

In Compass (all versions up to 1.10.1.0) long running queries give no feedback when running or when completed. As a result you have to spot the number of results changing to determine if a query is complete. I have attached a screen capture demonstrating this. Sorry about the background noise on the video. I was in an airport lounge
