I have written a Chrome extension that will alert you whenever a new topic is created on SFF.
The alert will appear in the bottom right of your screen and if you click it, it will open the topic in your browser.
You will only receive one notification per topic, even if you close your browser, or restart your machine.
It's fairly basic just now, but I think it is useful. I wrote it primarily for myself, but I hope that others find it useful too.
Let me know what you think.
