Line marker


Before I reset my mac, While using Atom ( with nuclide plugin installed ) I was able to mark lines. ( clicking on left side of line numbers ).

After resetting my mac and installing Atom, I can’t find that option. I also tried many Atom plugins but I couldn’t find it. Please see the screenshot attached bellow ( I’ve putted dots on image to show what was it look like ).

Do you know the option / plugin name?

Thanks in advance!
