A Chrome extension* that shows console messages on the frontend. It's inspired by toast.log, but this one's free! It allows passthrough of console messages, meaning that messages go to both the console and this extension*. It also lets you use the console for more "complex" console features, such as console.table() and console.time(). There's still a bit of work to do, but if you'd like to give it a try, just download this repository and open the index.html file for a demo.
* It's not an extension yet...
