First of all, CONGRATULATIONS to this project it's awesome.
I'm using snowdog/frontools to compile all files.
I've created a child theme from snowdog/sass-blank-theme and I have one question...
What are the best gulp-sprite option? I need this for my project and I don't know where is better for this ...
I'd suggest to not use sprites at all, b/c we are not in 2010 anymore
Use SVG icons instead.
