Only choosing certain scripts/ styles for preloading

Hey,

It seems that Cloudflare has fixed the problem with 520 errors, so we can finally use the plugin, it works great, just one thing that I would like to see added.

The ability to choose which assets are preloaded, instead of just preloading all, as that can cause performance issues. If that is something you could add then that would be great.

Here’s the article from Cloudflare about the fix btw:
