Is this package possible to implement real-time (vs selecting text and triggering manually)?

I've been trying to set my editor panes to justify with CSS or any other strategy I can find, and I'm starting to think that text-align: justify and text-justify aren't supported by Atom. Can I ask how you achieve justification with your package and whether or not you can set it to automatically reflow text with justification, real-time?

I'd like to set Atom up like most other word processors, in which this option is pretty standard.

Also I should note that I write with markdown, and your package doesn't seem to be enabled with .md files. It has no effect on my selected text when toggled (right, left, justify, etc).

Thanks.
