Hi everyone,

Like the title says, it lets you test your page and then try different optimizations (preloading stuff, inserting HTML, executing arbitrary JS, etc) on the page without making any changes to your code.

It's something I've been developing over several years, and to which I've dedicated my full time over the past 7 months or so. Let me know what you think.
