I just went to download Xcode to do some Python programming, and it turns out the App Store gives no feedback for how far along you are in the install process. For something that’s a three gigabyte download, this is completely unacceptable. I had to open the Activity Monitor just to see that it was, indeed, downloading.
EDIT 1: It’s finished downloading, at least according to the Activity Monitor where my network usage dropped sharply. Still no feedback.
EDIT 2: Apparently all it did was download the “Install Xcode” application and I needed to run it manually. Would have been nice to receive some notification instead of just saying “Installing…”
