98% of the time those lengthy messages are useless, but the other 2% of the time they're critical to tracking down the problem.

A year or two ago Visual Studio added a pop-up that parses such lengthy compiler messages into a clickable tree list. I found it annoying at first, until I discovered I could dock it to the side, ignore it 98% of the time, but still go look at the details when relevant. This is an idea other compilers should copy.

Maybe ships should copy this approach too: issue fewer warnings, but provide a list of warning details for review when necessary.
