While downloading an application from the Mac App Store, you are presented with a progress indicator in Launchpad, like so:
For a large install (like Xcode, as shown) this doesn't provide a terribly useful picture of the download's performance (how fast it's going / how much longer it's likely to take).
Is there any way (perhaps via a command-line tool) to get a more-accurate look at the progress of an App Store download? Something more along the lines of, say, 585,789 Kb / 1,768,231 Kb Downloaded
