Project Manager - https://atom.io/packages/project-manager (this one is a must, IMHO)
Sublime Style Column Selection - https://atom.io/packages/Sublime-Style-Column-Selection
File Icons - https://atom.io/packages/file-icons
Sort Lines - https://atom.io/packages/sort-lines
...and a pile of linters is most of my setup.
When I use Sublime, I miss `terminal-plus` so much. And `pigments` works better too.
Here's my complete package list:
