Plugin that is able to insert custom CSS and JS to specific page

I am very grateful to creators of this plug-in, because now I can insert css file or javascript file into header or footer according to condition based on url. I started to use also CSS snippets and JS snippets and inserting them into specific pages according to url which is very helpful for performance issues. Feature that I did not try yet, but I am looking forward to try it is history of edits in particular snippets. Keep up guys, your are doing great job! ??
