Did some test on gtmetrix with my site and they suggest minifying javascript files. How can I make a plug in to do this?

Anybody? I am surprised there isn't anything out there like this in Moodle.

All of the Moodle JavaScript is minified before it is released. Most of the items you have listed are legacy YUI modules, that are unlikely to get any attention, as they are gradually being replaced. The only one I notice from your list that appears to be a modern AMD module, only claims a 1% possible reduction, which isn't really worth pursuing.

It might be worth double-checking that your are serving the fully minified versions of the YUI files - compare what is served with the smallest versions of those files on the server.
