Show HN: Retina Twitter Chrome Extension

Creator here. Just made this to scratch my own annoying itch that Twitter still looks so crap on retina displays.

It's super simple right now, just replaces the 48px avatars with their 73px versions. There's generally a bigger version of profile pics too but those don't keep to the square ratio so not using those yet.

It's my first attempt at a chrome extension. Pull requests highly welcome: https://github.com/jordn/retina-twitter
