I really wish the Chrome remote debugger allowed multiple websocket connections.
A while back I made chromesync [0] to automatically push changes to your local files directly in to Chrome. It means you can work in your own editor (whichever it is) as normal and have your js updated on the fly. For me, it's a great way to develop SPAs.
Unfortunately, all too often you need to inspect something in the Chrome dev tools - which causes issues because you can only have one debugger connected.
Someone created a proxy to handle multiple connections [1] but it requires running the Dev Tools in a separate tab via the proxy too. You can make it all work but it's a lot of moving pieces.
