Saad Quadri created a handy website that lists all ECMAScript Proposals. On one single page you can get a quick glimpse of all proposals and the current stage they are in.
Great to see that the various stages of the TC39 Development Process themselves —something I always mention in my ever-evolving talk on ESNext— get their own prominent place on the website.
You might find this site a little bit handier than the linked-to Markdown files from the official https://tc39.es/
