Scott.
I have the same problem …
It produces a massive ammount of files. Just on 2 weeks time my CSS folder is more then 4 GB …
I don’t think thats ok … The JS folder is also verry hugh!!!
I see it producing each day a massive amount of files …
Maybe it is because i had WP fastes cache as well and ive set to empty cahe a few parts a day ???
When this is anable i think i can’t use your plugin? I makes my site to big!
