This plugin embeds or in-lines image/css/js content into the page before it’s loaded. This really improves page load speed scores, and can really improve actual load time if either the network connection is not blazingly fast, server side caching is used, or a combination of the two.
Warnings that are commonly eliminated in page load speed testing tools include
Optimize images 
Leverage browser caching 
Remove query strings from static resources 
Specify image dimensions 
Minify JavaScript 
Minify HTML 
Avoid bad requests 
Avoid a character set in the meta tag 
Avoid landing page redirects 
Defer parsing of JavaScript 
Inline small CSS 
Inline small JavaScript 
Minify CSS 
Minimize request size 
Optimize the order of styles and scripts 
Put CSS in the document head 
Serve resources from a consistent URL 
Serve scaled images 
Avoid CSS @import 
Combine images using CSS sprites 
Use a Content Delivery Network (CDN) 
Reduce the number of DOM elements 
Make fewer HTTP requests 
Minify JavaScript and CSS 
Put CSS at the top 
Put JavaScript at bottom 
Avoid AlphaImageLoader filter 
Avoid CSS expressions 
Reduce DNS lookups
The cases where some of these may still pop up would be a limitation of this project https://github.com/aadel112/simple-thimble, and you’ll note that these are all limitations that are actively being developed to be fixed.
