I was just reflecting on some of the work our team has done and I found a project from 2017 that Robert Nyman and Eric Bidelman created. Browser Bug Searcher!. It's incredible that with just a few key presses you have a great overview of your favourite features across all the major browser engines. Source code available. This actually highlights one of the issues that I have with crbug and webkit bug trackers, they don't have a simple way to get feeds of data in formats like RSS.
