Just as a heads up I've included Flat Awesome + Dark in the latest Flat Awesome + update. By purchasing the light version of the Plus addition you now get the Plus Dark version.

This just brings the style up to date with 1.5.6, mainly correcting an issue in the search_bar.css template.
Additionally I've adjusted the content color. To upgrade backup your styles first of course, then simply import and overwrite your Flat Awesome style, the updates will trickle down to your custom child style.
This is a minor update to Flat Awesome Dark, here's what has been fixed:
Updated to 1.4.5
Updated Font Awesome to 4.3.0
Z-Index issues which caused the Facebook sharing to be partially hidden should be corrected now
Removed random extra div I typed in by accident in the footer
Replaced Closed Icons so they work on all overlays which should have a close button
Fixed a .Responsive specific CSS for the editor icons
Fixed double close icon showing on notices
Changed our copyright slightly
To upgrade backup your current Flat Awesome Dark style + your child style XML's. Upload the new /styles/flatawesomedark/ folder then import and overwrite using the new Flat Awesome Dark.xml, all fixes will trickle down to your child style.
