I've been waiting for the kick in the pants to finally add js error tracking.

This looks great. At my previous company, I set up Errorception (https://errorception.com/) and it was a good step, but I'm excited by the production-side logging possibilities that track js offers, and the timeline feature.

I've just now added it to my current company (https://zoomforth.com), and would be happy to report later on how it works out!
