I made a Google Chrome extension to quickly create new repls, no matter what page you're on! While I did initially make this for personal use, I hope other people can find a good use for it and save yourself a bit of time. If you would like to download it here's a link to the chrome web store.
Let me know if you like it or have any issues. (I am aware that you get a message that says the extension is not in the webstore, that will hopefully go away sooner or later. I'm pretty sure it's because it just got accepted.)
