Git blame gutter with pull requests, related issues, and age color-coding of code.
This is a maintained fork
Since the original project it's no longer maintained, I decided to fork it and support it here. Thanks a lot to StepSize for the original work.
Better Git Blame Atom package 
A better way to view git blame info in Atom.
What makes it better?
TL;DR: it does more than just display git blame annotations in the gutter – it helps you visualise the blame info including the age of the code.
A rich popover displays summary info about the commit and visualises the commit's age.
Line highlighting makes it clear which other lines were introduced by the blame commit.
Oh and it's also fast and nicely designed.
How do I use it?
Use ctrl-b to toggle the blame gutter.
Alternatively, right click the file you want to blame and select Toggle Better Git Blame, or search for this command in the command palette (cmd-shift-p).
Hover over the blame text to display the popover & line highlighting.
How do I get setup?
Run apm install better-git-blame and restart Atom. You can also install it from Atom's Settings pane.
