Creator here. Just made this to scratch my own annoying itch that Twitter still looks so crap on retina displays.<p>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.<p>It's my first attempt at a chrome extension.
