Hello fellows,
I'm wondering if is possible to extract only the script that I need to use on my app from main pie.js. For ex I have a page with 120 input [type="text"] fields and if I want to apply some round corners for each input the page is loaded in 7 seconds.
Will be nice to be splitted in sections. section 1:round corners, section 2: box-shadow. etc and if I want to use only round corners to load only that roundCornersScript.js instead all pie.js.

Splitting up the JS file isn't going to help you much unfortunately. The real cost is in rendering -- 120 elements is going to be slow even if only the border-radius code is executing.
