@pirhoo done https://github.com/FGRibreau/node-nice-console thanks for the idea !

Brilliant! And I was going to say to put it in npm.

FYI, I had an issue with tests failing intermittently, was async timing issue, so step-through debugger really won't help, lots of console.log() in lots of places, but hard to see where the timing issue was. This just clarified everything.

This is very helpful, thanks!
