It is a very helpful plugin

Simple, but does what expected. It may depend on the theme, yet with my Storefront it worked well. There are not all styles available, but the main ones and I could see the effect live on my site. That was helpful for the decision, which fonts work well together and look good. I had to fix something in the css file but this plugin helped me a lot. I can recommend it. Thanks to the coder(s).
