I was looking on the files of the theme and from wordpress 4.6
And it came that some files (js or CSS) have ‘.min’ included on their file name.
Can i add those files manually to W3 Total Cache Minifier? Since the Auto option can make conflits.
The tweak of the theme speed could be documented on the support section, just the js and css of the theme, not from the wordpress. But i bet that many users would come to read some tutorial about it =]
