Show HN: Fetcher: grab posts that you used to refresh manually (github.com)

Hi all, I've created a chrome extension that fetches the posts from websites I usually refresh manually from.

I read alot of reddit, and twitter, and hackernews, and I grew addicted to refreshing to get new updates. This extension does that for me, and filters posts which I have already seen. Happy to get any feedback/PRs! :)
