I've recently found myself going to the GitHub website multiple times a day to gather context on the code I'm looking at in my code editor.
I looked at some VS Code extensions which allow you to view a "git blame" inside VS Code but I didn't really like any of the ones I tried.... so I thought it'd be a fun evening project to build one.
Introducing "Simple Git Blame". Install it, go to a file, select a line (or multiple) and summon the action. The "Blame" page will open in your browser.
You can view the source code here.
