Hi! and congratulations for this plugin!
I'm caching in client side all static files as JS scripts for server performance and better user experience.
I would like to know if you are considering (or it's possible) to include the JS script for your plugin in a 'regular' cacheable way like:
could save 13KB's on every page load (or 4 KB if gzipped)
also including the version number as many other plugins do is a good idea as it will invalidate the client side cached version:
