Disclosure: This package was created for learning purposes. After finishing it I found a package that does much more than this one. Check it out in: https://github.com/davidleghorn/atom-focus-mode
Allows you to focus on the selected line/text.
ctrl+alt+n on windows/linux or
cmd+alt+n on mac to toggle the focus.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
