The only change in Fargo 1.49 was that Font Awesome 3 has been replaced with version 4.
This was not a small change, unfortunately, even though the goal was to make it appear as if it was a small change. Please watch for breakage.
While I was working in this area I made it so that the left and right arrow keys move between panels in the Icon Chooser dialog (accessible from the Outliner menu in Fargo).
I also updated the GitHub project.
Font Awesome is still very awesome.
But I wish they wouldn't rock the boat so much.
We've baked in support for this excellent toolkit deeply in Fargo. Such deeply integrated things are not easily replaced, especially when lots of small seemingly unnecessary changes are made.
